Want to make a fun, simple, and quick project with a child but don't have a lot of supplies or ideas? Try making a paper helicopter. When you drop this helicopter from your hand it will slowly spin until it reaches the floor. You will only need a piece of paper to make it but you will see how much fun can be had with a very simple toy.

Making a Paper Helicopter

• Large index cards, usually 5 inches (12.7 cm) by 7 inches, work really well for this project. Use one if you already have some at home.
• These measurements do not need to be totally exact, so don't worry if you are a little bit off. What matters is that the paper is much longer than it is wide.
• Is possible, draw your lines using a ruler so your cuts are straight.
• This is not totally necessary but may help you to make a good helicopter.
• If you drew the guide lines on your paper, be sure to stop cutting at least a half an inch before you get to the middle line. This will assure that you do not accidentally cut too far.
• Once again, the guide lines you might have drawn on your paper may help you. When cutting these horizontal cuts, be sure not to cut so far that you reach the middle line. It's best to only cut halfway to the middle line on both sides you are cutting. This will assure that the bottom of your helicopter doesn't get cut off!
• Once you have folded and creased them, open these flaps up halfway. They have now formed the wings of your helicopter.
• Experiment by dropping it from different heights. See if the way it flies changes.
• Use various sizes of paperclips, see which works best.
• You can also cut the wings, so they are thinner or thicker, to get the best flight.

Making a Really Simple Small Paper Helicopter

• The width of your index card will now be one quarter what it was to begin with.
• Once both sides are folded, open them both up halfway. These folds have now formed the wings of your helicopter.

Community Q&A

• Before you cut your paper you can decorate it, so that your finished helicopter is fun and colorful. [8] X Research source Thanks Helpful 0 Not Helpful 0
• Bend the wings upwards slightly. This will make it spin sooner. Thanks Helpful 0 Not Helpful 0
• Make sure the paper is not used, messed up, or crinkled. It messes up the spin. Attach it to a helicopter shaped paper. Never throw it. Use a launcher. Thanks Helpful 0 Not Helpful 0

• Be careful when using scissors. Try not to cut yourself or others. Thanks Helpful 24 Not Helpful 35

Things You'll Need

About This Article

To create a paper helicopter, cut a piece of paper to be 2.5 inches wide and 7 inches long. Next, fold your paper in half lengthwise, crease it, unfold the paper, and lay it flat. Then, cut halfway down the crease and make 2 small cuts in toward the center line. Fold both of the bottom sections down in opposite directions, crease them, and open these flaps up halfway to form the wings of your helicopter. Lastly, slide a paperclip on the bottom of the helicopter to hold the bottom flaps closed and give your helicopter a spin! For tips on drawing guidelines to help you make clean folds, read on!

A paper helicopter experiment is a fantastic hands-on, and low-budget way for students to explore cause and effect relationships in experimental design. These models offer teachers easy STEM activities with paper and generate authentic data in the classroom. In fact, there are so many paper helicopter materials, lessons, and instructions online, it’s hard to know where to start!

Simple quantifiable scenarios can be examined and several criteria for success can be defined and explored. Paper helicopters provide educators with easy-to-do experiments to help students learn the scientific method.

The ASTC Science World Society concisely explains the many levels of inquiry teachers can offer students when conducting paper helicopter experiments. These levels of investigation range from more structured to less structured which suits various grade levels and abilities.

Paper helicopter lessons with more structure would generally target lower grade levels. More open assignments are suitable for independent students at the higher grade levels where the teacher acts as a facilitator. Teachers of all experience levels can take advantage of the learning opportunities provided by experimenting with paper helicopters.

Paper Helicopter Lesson Outline

The specific paper helicopter lesson outlined in this blog post targets students in upper elementary and middle school. It can be extended above and below these grade levels as well. This lesson covers methods of data gathering and provides teachers with easy-to-use activity resources.

This paper helicopter experiment is a simple introduction to experimental design and will target this testable science question:

Does changing the blade length of a paper helicopter affect how long it stays in the air? (Keep reading, however, this question needs a bit of clarification.)

The NGSS Standards do apply! Examples:

• 3-5-ETS1-3 Engineering Design – Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence, using fair tests in which variables are controlled and the number of trials considered.
• MS-ETS1-2 Engineering Design – Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.

How Does a Helicopter Work?

In basic terms, an actual helicopter is a type of aircraft that creates lift (an upward force of air) with horizontally spinning rotor blades. These rotor blades are sometimes referred to as simply rotors or blades.

The physics of paper helicopters are different from real helicopters. Traditional paper helicopters do not use a power source to spin their blades and create lift. These models are typically created with two blades and dropped from a fixed height and spin as they descend.

Paper helicopters spin because of the earth’s gravity, lift, and configuration of the rotors. When dropped, the helicopter’s mass experiences gravity, and it naturally falls to the floor which causes paper blades to bend slightly upward due to lift. The lift force of the air pushes on each of the blades equally but in opposite directions, horizontally and vertically. As a result of the horizontal equal, opposite, and offset forces, the helicopter spins around as it descends.

The helicopter descends due to unbalanced forces: The weight of the helicopters is greater than the lift force of air.

2BrokeScientists studied the airflow around a helicopter and found that there were high-pressure areas under the blades. This high pressure results in equal and opposite opposing forces that cause the spin.

Framing the analysis in terms of Newton’s Third Law of Motion , a pair of equal and opposite forces acting horizontally under each blade and on the body of the paper helicopter cause rotation.

Simple Paper Helicopter

A simple paper helicopter can be made easily at home or school. Multipurpose U.S. letter-size printer paper (8.5 x 11 inches, 21.6 x 27.9 cm) works well for the model. The design is simple to make with only a few cuts and folds, and its parts can be easily adjusted to examine changes regarding flight behavior. To conduct the paper helicopter experiment, we should know the parts first!

Paper Helicopter Parts

The paper helicopter parts are similar to a real helicopter’s parts. The common paper helicopter with two blades has four major parts:

Blades – These two parts are identical rectangles arranged vertically at the top of the helicopter. These parts are sometimes called rotors , blades , rotor blades , wings , or even propellers . The blades provide the lift and are factors that cause the helicopter to spin. The width of the two blades together equals the width of the paper template used to make the helicopter. The thickness of the blades is one layer of paper.

Body – The top of the body of the paper helicopter connects to the blades. The body shape is a rectangle and is perpendicular to the blades. It is located between the blades and the tail. It is as wide as the paper template used to make the helicopter. The thickness of the body is one layer of paper.

Tail – The top of the tail connects to the bottom of the body. The thickness of the tail is three layers of paper. The width of the paper helicopter tail is one-third the width of the template. The tail provides the paper helicopter flight stability.

Stabilizer – The stabilizer is essentially the bottom tip of the tail. A horizontal fold in the tail creates the stabilizer. This fold also provides the paper helicopter flight stability by shifting the model’s center of mass downward.

Independent, Dependent, and Controlled Variables

The paper helicopter experiment requires that you control some variables, change others, and look for cause and effect. A variable is a characteristic or quantity that can be measured or counted in an experiment. Most experiments for this age group account for three kinds of variables: independent, dependent, and controlled.

Independent variables are manipulated by the researcher. These variables are changed and studied to determine if they are the cause in a cause-and-effect relationship. Independent variables are not influenced by other variables. Sometimes independent variables are not manipulated by the researcher but monitored to see how their changes may affect other variables. For example, time (seconds, days, years) is an independent variable that can be tracked to see how it may affect other variables (e.g., the growth of a plant).

Dependent variables are what researchers observe, measure, or count in an experiment. Changes in dependent variables depend on various influences. Independent variables are factors that may change a dependent variable.

Why are Variables Important in an Experiment?

That’s the point of an experiment: To find out what may or may not influence a dependent variable! These types of variables are the “effect” in a cause-and-effect relationship.

Controlled variables are variables that the researcher does not allow to change. The variables are maintained to be constant so that they do not influence any of the dependent variables. Variables that are kept the same for every measurement and test in an experiment, ensure that the dependent variables produce data that are as accurate as possible.

Knowing variables’ roles helps researchers be systematic with their observations, accurately collect relevant data, and be logical with their scientific thinking.

How Do You Make a Paper Helicopter Fall Slower?

A common problem to examine is how to make a paper helicopter fall slower. In other words, many paper helicopter designers want to know how to make a paper helicopter that stays in the air the longest. A simple two-rotor paper helicopter is a good design choice to study this common problem.

The researcher can manipulate any of the four helicopter parts to determine what factors affect the flight time of a paper helicopter. By adjusting a part of the helicopter, researchers are manipulating the independent variable to determine if this change affects the time the helicopter stays in the air (time in the air is the dependent variable). Parts of the helicopter that do not change from a standard model to an adjusted model, are considered control variables.

Paper Helicopter Variables

To ensure that testing is fair so that cause-and-effect data are a reliable source of information, the three types of paper helicopter variables need to be defined. For our paper helicopter experiment example, the independent, dependent, and controlled variables are identified as follows.

I ndependent Variables :

• blade length (which changes the body height)
• body height (which changes when the rotor blade length is adjusted)

Dependent Variable :

Controlled Variables (Helicopter Parts):

• rotor blade width and thickness
• body width and thickness
• tail length, width, and thickness
• stabilizer length, width and thickness

Controlled Variables (Materials and Conditions):

• paper size and mass
• drop height
• drop start time

From a persnickety perspective, there are more variables to control like the angle between the blades and the body. This should be 90 degrees by the way. How deep you go as far as what variables are controlled–what you look at–depends on the students’ age group and experience.

By taking into account the types of variables in an experiment, our actually scientific inquiry question for the paper helicopter experiment is:

Does changing the blade-length-to-body-height ratio of a paper helicopter affect how long it stays in the air?

It’s important to note that since paper helicopters easily offer many cause-and-effect relationships to explore, students may eagerly start changing parts of the helicopter to see what happens–how flight changes. Once students get their hands on a template, without focused guidance, teachers may see many different configurations, and helicopters being thrown up into the air.

The time to be creative with designs to more freely explore flight dynamics is after a procedural scientific experiment is conducted.

Paper Helicopter Experiment Considerations

If you are conducting the paper helicopter experiment in a classroom, you will need to set up a testing area. Two paper helicopter models are needed as well to explore how to make a paper helicopter fall slower. It may be easiest to refer to each model by their blade lengths: shorter-blade model and longer-blade model.

The student tester usually holds the completed helicopters away from their body and just above their head while standing on a chair. This drop distance is sufficient for comparing two different helicopters. Make sure there is enough clearance between the tester and any objects or observers to not interfere with the paper helicopters’ descent (i.e., to avoid introducing unwanted variables).

Having multiple students drop the two different helicopter types from the same height and at the same time can provide a simple and solid experimental design.

Here’s an example from NASUWT showing three students testing paper helicopters at once:

How Many Trials Should a Good Experiment Have?

What is a trial in a science experiment? A trial is one of many tests that make up the experiment itself. For example, each time you drop the paper helicopter from a fixed height to see if increasing the blade length increases how slowly a paper helicopter falls, you are conducting a trial.

We want a good experiment–one that offers fair testing and produces not only accurate data but lots of accurate data. The more trials we have, the more evidence we have that random factors are not influencing the outcome.

Other ways to think about the role of trials are: How many trials in an experiment should you conduct to get valid results? How many trials are required to validate a hypothesis? We want the results to truly represent what we are investigating.

So, how many trials should a good experiment have? As many as possible. Three trials minimum seems to be a consensus. With easy-to-test paper helicopters, students can conduct many trials in a short period of time. Multiple helicopters can be tested at once as well. With a design such as the aluminum foil boat investigation , fewer trials are possible because it takes more time to prepare and test.

How to Collect Data in a Science Experiment

If you can gather as much good data as possible without too much logistic fuss, do it! For example, provide half of your class with the shorter-blade paper helicopter template. The other half of the class would be given the longer-blade helicopter template.

When ready, the two helicopter groups could be separated, face each other, hold up their models at the same height, and then drop them simultaneously. Repeat as needed. Students should keep their hands and arms as far away from the helicopters as possible, holding the tips of the blades before release.

Videos of the experiment offer easily reviewable data that would offer a more sound determination to see if longer or shorter rotor blades cause a paper helicopter to stay in the air the longest. Each model type should be clearly identified especially if relying on videos for data analysis.

Other Ways to Collect Data

There are other ways to collect data while ensuring a fair test. Establishing a fixed height from the floor (i.e., controlling the distance-flown variable) can be done by hanging a small mass from the classroom ceiling with thread.

One successful set-up I have used has a paper clip on one end of a thread with a piece of blue painter’s tape on the other end. The top end with the paper clip is tucked into the metal drop ceiling frame grid, and the piece of blue paper tape has enough mass to hang down properly and be easily visible. I prefer not to have a paper clip hanging on the lower end because if hit or smacked for “fun” it could hurt someone’s hand, stick in the ceiling, etc.

A distance of 200 cm from the tape to the floor is a good distance to establish as a controlled variable for dropping and observing paper helicopters. Place six to eight of these paperclip-thread systems around the classroom to create testing spaces for groups of two to four students.

Paper Helicopter Flight Times

The easiest and quickest way to determine which paper helicopter model falls more slowly may be the aforementioned multi-copter drop method with or without a video recording. So, if you need a quick and easy STEM activity, go this route.

Another way to perform a fair test requires a stopwatch. After setting up the six to eight test stations around the classroom with the paperclip, thread, and blue painter’s tape, each group of students can perform the 200 cm drop and time the helicopter models multiple times.

If students do, say, ten trials for each model they should have sufficient data to minimize random factors. Each group’s ability to time the drops accurately will factor into the integrity of the results. Measuring the paper helicopters’ times over a fixed distance will also produce data that can be analyzed mathematically. Some examples of mathematical analyses are:

• represent and interpret data in a chart or graph
• measures of center (e.g., average time for each model)
• measures of variability (e.g., differences in trial times for each model)

Other Simple Paper Helicopter Launcher Ideas

There are other ways to launch paper helicopters rather than dropping them from your hand. For example, two meter sticks, side-by-side, can launch two to four helicopters at once. Two people are needed to hold the ends of the meter sticks. A bit of practice helps to keep the sticks level at a prescribed height and to separate them at the same time for launching.

With the two-stick method, you can launch even more helicopters at once using longer pieces of wood. Consider using two 1 in. x 2 in. x 8 ft. furring strip boards for launching seven to ten paper helicopters at once with just two people.

Paper Helicopter Experiment Lesson Plan

The focus of this paper helicopter investigation explores how the independent variables of blade length and body height together affect time aloft. Remember that, the blade length cannot be changed without changing the body height (unless we change the mass, which is a variable we are controlling). This means for both types of helicopters:

Blade length (shorter) with body height (taller) = equals = Blade length (longer) with body height (shorter)

And, as a reminder, our paper helicopter scientific inquiry question is:

Lesson Plan Parts and Documents

Paper Helicopter Template – There are four free printable pdf templates (8.5 x 11 inches, 21.6 x 27.9 cm). Each helicopter template is one page with the two types of helicopters:

• paper helicopter template with instructions and labels
• paper helicopter template with instructions (no labels)
• paper helicopter template with minimal instructions
• paper helicopter template no instruction (just cutting and folding lines)

Choose the template that makes the most sense for your students. Generally, the lower the grade level, the more instruction, and guidance are needed to make a paper helicopter.

Teacher Lesson Plan Outline

Grade Levels 4 – 7 (8 – 10 works too!)

Time How deep do you want to go? What is the grade level? Are you looking for a quick STEM activity or a long-term stem project ? Consider 45 minutes (one class) to 90 minutes (two classes), and keep in mind any extension activities.

Scientific Inquiry Question Does changing the blade-length-to-body-height ratio of a paper helicopter affect how long it stays in the air?

If you’re working with lower grade levels, or want to simplify the question, pose it like this: Does changing the blade length of a paper helicopter affect how long it stays in the air?

Fold the longer length of the paper strip and secure it in place using glue. This will form the main body of your helicopter.

Congratulations! Your paper helicopter is now ready to take to the skies. Hold it at a height and release it, observing its captivating motion.

Flight Dynamics: The Science Behind the Spin

As your paper helicopter gracefully descends, let’s explore the scientific principles governing its flight. The phenomenon can be understood as follows:

• The force of gravity pulls the helicopter downward, setting the stage for its aerial adventure.
• Simultaneously, the air rushes out from under the wings of the helicopter in all directions.
• This rush of air creates resistance, pushing up against each blade of the helicopter individually.
• As a result, a fraction of the initial thrust is redirected sideways, generating a horizontal push and initiating the mesmerizing spinning motion of the helicopter.

STEP 4: Take your paper helicopter outside and toss into the air! How long can it stay in the air?

THE SCIENCE BEHIND THE PAPER HELICOPTER

Unlike airplanes, helicopters have rotor blades which spin horizontally. It is the spinning of the blades that creates lift, which is an upward force of air.

When your pinwheel helicopter falls it is due to the force of earth’s gravity. Lift and the design of the rotors help it stay in the air.

It naturally falls to the ground which causes the paper to bend slightly upward due to lift. When your paper helicopter falls, air pushes up against the blades, with equal force, and the shape causes the copter to spin. This is because the blades are designed so that the upcoming air is captured and pushes the blades in one direction.

Ask an Explainer

How do paper helicopters work.

When you make a paper helicopter, you're making a propeller . Tilting the blades will enable the propeller to produce lift by creating faster moving air on the top, which has less pressure than on the bottom. If spun right, the paper helicopter will fly into the air! If dropped from a high point, it will circle gently to the ground.

How to Make a Paper Helicopter: A Step-by-Step Guide

Table of Contents

Are you looking for a fun and easy DIY project for a lazy afternoon? Making a paper helicopter is an excellent way to spend your time and boost your creativity. In this article, we will provide you with a step-by-step guide on how to make a paper helicopter that can fly. Let’s get started!

Materials Needed

Before we begin, let’s gather all the materials we need. Here’s a list of everything you need to make a paper helicopter:

• A4 or letter-size paper
• Markers or colored pencils (optional)

You can use any kind of paper you have on hand, such as printer paper, notebook paper, or construction paper. Tape and paperclips are essential for weighting the helicopter and keeping it balanced while in flight. If you want to add some color to your helicopter, markers or colored pencils are a great addition.

Once you have all the materials, let’s move on to the next section, where we will provide you with a detailed guide on how to make a paper helicopter.

Steps to Make a Paper Helicopter

Step 1: Start by taking a piece of paper and folding it in half lengthwise. Make sure that the edges are aligned correctly, and the crease is sharp.

Step 2: Next, unfold the paper and fold each corner towards the center crease. This will create two diagonal folds that meet in the middle.

Step 3: Fold the paper again along the center crease, this time in the opposite direction. Make sure that the folds are sharp and precise.

Step 4: Take one of the top corners and fold it down to meet the center crease. Repeat this step with the other top corner of the paper.

Step 5: Now, fold the paper in half along the center crease, so the top corners meet the bottom corners.

Step 6: Fold the paper in half again, but this time, fold it widthwise. Make sure the edges are aligned, and the crease is sharp.

Step 7: Cut along the folded edges, stopping at the center crease. This will create four flaps.

Step 8: Fold each flap towards the center crease, making sure that they are all folded at the same angle.

Step 9: Fold the helicopter in half, so the flaps are on top of each other. Secure the flaps with a paperclip.

Step 10: Finally, attach a small piece of tape to the bottom of the helicopter. This will act as a weight and keep the helicopter balanced while in flight.

Congratulations! You have successfully made a paper helicopter. But wait, there’s more! In the next section, we will provide you with some tips and tricks to make your paper helicopter fly even better.

Tips and Tricks

Now that you have made your paper helicopter let’s make it fly better with some tips and tricks. Here are some ways to improve your paper helicopter’s performance:

Adjust the Weight

The weight of your paper helicopter is crucial to its flight. If it’s too heavy, it won’t fly at all, and if it’s too light, it will fly too quickly and crash. To adjust the weight, you can add or remove paperclips. If your helicopter isn’t flying well, try adding more paperclips to the bottom.

Adjust the Flaps

The angle of the flaps on your helicopter can also affect its flight. If the flaps are too flat, the helicopter won’t spin, and if they are too steep, it will spin too quickly and crash. To adjust the flaps, try folding them at different angles until you find the perfect balance.

Add Decorations

Adding decorations to your paper helicopter not only makes it look cool but can also help with its flight. You can draw designs on the paper or attach small pieces of paper to the flaps to add weight and improve stability.

Test Different Heights

The height from which you drop your helicopter can also affect its flight. Try dropping it from different heights and see how it performs. Dropping it from a higher height will give it more time to spin and glide, while dropping it from a lower height will make it spin faster.

By implementing these tips and tricks, you can make your paper helicopter fly better and have more fun with it.

Variations of Paper Helicopters

Now that you know how to make a basic paper helicopter, it’s time to get creative and try different variations. Here are some designs you can try:

Dragonfly Helicopter

The dragonfly helicopter is a unique and fun variation of the basic paper helicopter. To make it, fold the paper as you would for a regular helicopter, but instead of folding the flaps towards the center crease, fold them towards the back. This will create a dragonfly-like shape that spins and flies differently from the regular helicopter.

Double Helicopter

The double helicopter is another exciting variation that involves making two helicopters and attaching them together. To make it, follow the steps to make two regular helicopters, then tape them together at the bottom. When you drop it, both helicopters will spin simultaneously, creating a unique flying pattern.

Pinwheel Helicopter

The pinwheel helicopter is a more complex design that involves cutting the paper into a pinwheel shape. To make it, start by folding the paper in half diagonally, then cut along the folded line. Cut each of the resulting triangles in half again, then fold each corner towards the center. Attach a paperclip to the bottom, and your pinwheel helicopter is ready to fly.

With these variations, you can create unique and exciting paper helicopters that will keep you entertained for hours.

Now that you know how to make a basic paper helicopter, it’s time to get creative and try different designs. Here are some variations of paper helicopters that you can make:

The Dual-Blade Helicopter

Instead of having four flaps, this design has two flaps that are wider and shorter than the original design. The helicopter spins as it falls, creating a unique flying pattern. To make this design, follow the steps for making a basic paper helicopter, but instead of creating four flaps, create two wide flaps.

The Propeller Helicopter

This design features a small propeller that spins as the helicopter falls. To make this design, cut out a small rectangle from the paper, making sure that the width is less than the length of the paper. Fold the paper in half, lengthwise, and cut two slits on the folded edge, about 1 cm apart. Fold up the two flaps, creating a propeller shape. Follow the steps for making a basic paper helicopter, but instead of creating four flaps, attach the propeller to the top of the helicopter with a paperclip.

The Dragonfly Helicopter

This design mimics the movement of a dragonfly in flight. To make this design, follow the steps for making a basic paper helicopter, but instead of creating four flaps, create two long, thin flaps. Cut out two small rectangles and attach them to the bottom of the flaps with tape. This will act as a weight and keep the helicopter balanced while in flight.

Making a paper helicopter is a fun and easy DIY project that anyone can do. With just a few materials and some simple steps, you can create a paper helicopter that can fly. Whether you make a basic design or try different variations, making paper helicopters is an excellent way to spend your time and boost your creativity. So, what are you waiting for?

Learning Design of Experiments with Paper Helicopters and Minitab

Topics: Design of Experiments - DOE , Minitab Statistical Software , Articles

This article was written by g uest blogger Matthew Barsalou , Statistical Problem Resolution Master Black Belt and Engineering Quality Expert at BorgWarner Turbo Systems Engineering GmbH with over 15 years of experience in quality. 

The late statistician George E. P. Box, along with Soren Bisgaard and Conrad Fung, used a paper helicopter to teach statistics. The idea originated with Kip Rogers of Digital Equipment and is useful for demonstrating factorial designs. Decades after Box, Bisgaard and Fung’s publication, the DOE helicopter has become a useful staple of DOE training.

The paper helicopter provides a way to quickly explain basic DOE concepts. It also offers an easy-to-do experiment you can analyze using Minitab.

We can’t just declare we want a high-quality helicopter. Quality must be clearly defined.

To perform a DOE with a paper helicopter we need to identify the desired output, which would be our response variable.

A good helicopter is one which stays in the air for a longer time, so the response variable would be flight time as measured from the time the helicopter is dropped from a height of 2 meters until the time it hits the floor. Without defining the test conditions it could be possible that sample helicopters would be dropped from different heights, in which case our DOE results would be not be valid.

Test factors that influence flight time must also be identified. For the helicopter experiment, the factors could be paper type, rotor length, leg length, leg width and paper clip. The helicopter experiment levels are varied by using two different types of paper, using longer or shorter leg and rotor lengths and adding or removing a paper clip.

Here’s how to make the paper helicopters.

• Step 1: Cut the paper to a width of 5cm.
• Step 2: Cut the paper the length of paper rotor length plus leg length, and add 2 cm for the body.
• Step 3: Cut dotted lines at Leg A and Leg C. The length of each cut is 5 cm minus leg width divided by 2.
• Step 4: Fold leg A onto leg B.
• Step 5: Fold leg C onto leg B.
• Step 6: Fold rotor A and rotor B in opposite directions. They should form 90° to the body and be 180° away from each other.
• Step 7: For the paper clip version: Add a paper clip to the bottom of the leg

Table 1: Helicopter factors

Designing the Experiment

Statisticians and Six Sigma black belts should know how to set up and perform the calculations in a designed experiment by hand. However, computer programs make DOE a much simpler task, particularly for people who need to perform experiments only occasionally.

To create a fractional factorial design in Minitab Statistical Software, go to Stat > DOE > Factorial > Create Factorial Design where we can select the desired design.

Resolution is the degree to which effects are aliased with other effects. In other words, aliased effects are mixed and can’t be estimated separately. This can also be referred to as confounding, and it results from not testing every possible combination of factors.

This is a disadvantage of a fractional factorial design. However, not testing every possible combination can be a significant advantage in time and expense over a full factorial design. If you’re not sure what resolution you should use, click on Display Available Designs… to see a list of designs and resolutions.

We typically use three levels of resolution: Resolution III, IV and V. There is no confounding of main effects with each other in these three resolution types; however, in a Resolution III design, main effects will be confounded with 2-factor interactions. This is a problem because 2-factor interactions are quite common in practice. Resolution IV designs do not have 2-factor confounding with main effects, but 2-factor interactions are aliased with other 2-factor interactions, and main effects are confounded with 3-factor interactions.

We try to use Resolution IV designs instead of Resolution III designs when possible because they have less aliasing, but still require fewer experimental runs than higher resolution experiments.

Resolution V designs have the added advantage that no 2-factor effects are confounded with other 2-factor effects; however, 2-factor effects are aliased with 3-factor effects, and main effects are aliased with 4-factor effects. This is a good thing, as 3-factor and above interactions are rarely significant in practice.

The confounding problem can be eliminated by performing a full factorial design. However, this requires more experimental runs, which might be prohibitive in terms of both time and money.

Looking at the Display Available Designs… option in Minitab, we can conduct a fractional factorial experiment using either a Resolution III or a Resolution V design for the 5-factor helicopter experiment. A Resolution III design would only need 8 runs, but because of the extreme confounding, the Resolution V design that requires 16 test runs is the better option. Click on Designs… and select the desired design.

As you set up the experiment, Minitab also asks for the number of blocks. Blocks are simply homogenous groupings of measurements that can be used to account for variation. The default value is one because, ideally, everything is homogenous.

The helicopter experiment will be set up so that there is only one experimental block. Each type of paper will come from the same source. The helicopters will all be built by the same person using the same scissors and ruler. If we used paper clips from two manufacturers or had some other potential causes for variation, then we would need separate blocks. Fortunately, this is not the case.

After you select your design, click Factors to enter the names and levels of the variables in your experiment. To change the name of a factor, type the name of the factor over the letter in the name field. The factor settings can also be renamed by replacing the default values of -1 and 1 with the actual factor levels.

When you’ve completed the dialog box, Minitab creates the experimental design and displays it in a Minitab worksheet. The Session Window above the worksheet provides a description of the selected design with the resulting alias structure.

In the resulting Minitab worksheet, the experimental results are entered into column C10. We can name the column “Flight time” because that is our experimental response variable.

A randomized run order is provided in the “RunOrder” column. Without randomization there is a risk that the experimental results will reflect unknown changes in the test system over time – such as if the scissors grow dull, resulting in slightly different cuts.

Minitab’s default setting for a designed experiment is one replicate. If you observe a lot of variation in the process or the resulting measurements, you can use Stat > DOE > Modify Design to add replicates to your design. Suppose the person making the helicopters had difficulty cutting a straight line so all edges are not uniform; the differences in results may reflect this variation. Replicating runs minimizes the effects of this kind of unanticipated variation.

Gathering the Experimental Data

Variability can have a major impact on experimental results, so take steps to reduce the variability. Have the same person make all helicopters and have them use the same pair of scissors and ruler. Drop the helicopters from a height of 2 meters, and identify the drop point clearly to ensure consistency. A higher or lower starting point would affect flight time, and this could throw off the results. The helicopters must also be held and released the same way, or variation in our data might be the effect of the release method and not the design of the helicopter.

The Minitab worksheet below contains the experimental results listed under “Flight time” in column C10.

Analyzing the Data

After running the experiment and entering the collected data in the Minitab worksheet, select DOE > Factorial > Analyze Factorial Design…

Significant factors are those that influence the response as they changed from one setting to another. When you click OK, Minitab provides an ANOVA table as well as a Pareto chart of effects, which make it very easy to identify significant factors.

With all our factors included in the model, we have no degrees of freedom left for Error, and you need at least 1 degree of freedom to calculate p-values. But while we can’t accept this model based on the ANOVA results, we can use the normal plot or Pareto chart to identify factors and interactions that are not significant.

At this point, the experimenter would typically begin eliminating these factors, rerunning the analysis until only significant factors and interactions are left. This is usually referred to as “reducing the model.” As factors are removed from the model, additional degrees of freedom become available for the calculation of p-values. The number of models you need to evaluate depends on the number of factors in your analysis.

Reducing the model takes only one step with Minitab’s stepwise DOE tool. To use this feature, return to Analyze Factorial Design… (or hit Ctrl+E to open your most previous dialog box). Select C10 “Flight time” as the response, then click Stepwise…

The stepwise regression feature makes it simple and fast to select the optimal model for your data by automatically removing factors to find the model that best fits your data. You can choose from four stepwise analysis methods: Stepwise, Forward selection, and Backward elimination, and Forward Information Criteria. In Backward elimination, all factors are included in the initial analysis, and then non-significant factors are removed one by one. In Forward selection, we start with an empty model and search for significant terms. This can be a useful tool when you have a situation like we currently have: Too many terms with too few runs.

Regardless of the stepwise method you use, the model Minitab selects contains the same significant factors shown below:

To help you interpret your results, Minitab can also provide main effects and interaction plots. Select DOE > Factorial > Factorial Plots… Because we have already analyzed the results, Minitab automatically selects the factors used in our model:

Clicking OK gives us plots of the significant main effects and interactions. The main effects plot shows the results of changing from one setting to another for each factor. Be cautious with these. You can only directly interpret main effects that are *not* involved in a significant interaction. This is why we only select B and E, because the A*C interaction overrides the main effects.

The main effects plot shows we have longer flight times with the paper clip off, and longer rotor length. The interaction plot shows the interactions between the factors.

This interaction tells us about these two factors. With heavy paper, leg length DOEs not matter much. With light paper, leg length has a much larger impact. Here it shows us our longest flight is with light paper and short leg length.

Finally, we can use the Response Optimizer to find the combination of factor settings that will give us the longest flight time. Select Stat > DOE > Factorial > Response Optimizer… Our goal is to maximize the flight length.

The optimizer produces the following graph showing the optimal factor settings in red, and the predicted response for helicopters made with those settings in blue. Take note that factor D DOEs not appear, as our analysis did not flag it as significant. Because it has no statistically significant impact on flight time, we can choose the setting for Factor D based on other considerations, such as cost:

For the data we collected, our analysis with Minitab indicates the optimal helicopter settings are lighter paper, longer rotor length, shorter leg length, and no paperclip on the leg.

To design an even better helicopter, we could repeat the entire DOE using even lighter paper and longer helicopter blades. A 50 cm wing may be bigger, but that does not mean it will be better. You may be able to predict the ideal settings based on a DOE result, but you should always be cautious when extrapolating beyond the data set, or the result may be a crashing helicopter.

Make a paper mars helicopter.

• This lesson is also available as an independent activity for students .
• See tips for remote instruction in the Management section.

NASA's Perseverance Mars rover launched in July 2020, carrying the first helicopter to the surface of Mars ! This helicopter has to be lightweight and have large blades to fly on Mars. These large blades rotate so quickly that they generate enough lift to overcome the gravity of the Red Planet and lift off the ground.

In this project, students will build a paper helicopter. Then, just as NASA engineers had to try out different versions of the Mars helicopter before coming up with a final design, students will experiment with the design of their helicopters to see what works best.

Plain paper OR a copy of the template – Download PDF

Measuring tape

(Optional) 3-meter (10-foot) length of lightweight ribbon or smartphone camera

Have extra copies of the template or blank paper ready so students can make multiple helicopters.

Tips for Remote Instruction

• If you are teaching online and students do not have access to a printer, have them trace the template by holding up a piece of paper to their computer screen. Remind them to not press hard and damage their screen.
• If students are learning from home and they don’t have a measuring tape or ruler, have them select something to use as a nonstandard measurement tool. Pencils work well.
• If students are learning from home and do not have access to a piece of ribbon, have them tape thin strips of paper together to create a ribbon.

In July 2020, NASA launched the Perseverance rover to Mars. Traveling along with Perseverance is Ingenuity, the first helicopter designed to fly on Mars . A small autonomous aircraft, Ingenuity is designed to perform the first tests of powered flight on another world. In the months after Perseverance lands, the helicopter will be lowered from the rover's belly onto the surface of Mars to test powered flight in the planet's thin atmosphere.

Ingenuity will perform a series of test flights over a 30-Martian-day window that will begin sometime in the spring of 2021. (A Martian day, or sol, is 24 hours and 37 minutes.) For its first flight, Ingenuity will hover a few feet above the ground for about 20 to 30 seconds and land. That alone will be a major achievement: the very first powered flight in the extremely thin atmosphere of Mars! After that, the team will attempt additional experimental flights over a farther distance and at a greater altitude. Ingenuity’s performance during these experimental flights will help inform decisions about the future use of small helicopters for Mars exploration. Future Mars helicopters could serve as robotic scouts, surveying terrain from above, or they could function as stand-alone science craft carrying instrument payloads.

Designing a helicopter to fly on Mars was no small task. The Mars atmosphere is only 1% the density of Earth’s atmosphere, so generating enough lift to overcome the gravity of Mars is a challenge. The helicopter had to be lightweight with extremely fast rotors to be able to generate enough lift. Though a full outdoor test couldn't be done on Earth, engineers were able to simulate conditions on Mars inside a test chamber at NASA's Jet Propulsion Laboratory in Southern California. To do this, they offset Earth's gravity by attaching tethers to the helicopter that support about 62% of its weight. Then, they performed flight tests inside a vacuum chamber that pumped out approximately 99% of the air, leaving a very thin atmosphere. Months of design, testing, redesign, and retesting went into the development of the Ingenuity Mars helicopter. Though engineers came up with their best design and it worked well inside the test chamber, the real test is yet to come once the Perseverance rover lands on the surface of Mars, delivering Ingenuity to its new test environment.

In this activity, your students will experiment with simple paper helicopter designs, engaging in the engineering design process that NASA engineers use every day.

• Ask students to describe how a helicopter flies. Elements of their description should include fast-moving, horizontal, rotary blades.
• Explain that the rotary blades are slightly angled so they can push against the air and lift the helicopter off the ground.
• Ask students what else rotates and pushes against air (e.g., a fan). Ask students to compare and contrast a fan with a helicopter. For example, both move air in similar manners, but the helicopter moves a large volume of air downward while a fan usually moves a smaller volume of air toward us.
• Explain that a helicopter moves so much air with its large, fast-moving blades, that the force of the blades against the air can overcome the weight of the helicopter and push it up off the ground. The helicopter is working against the force of gravity – which is constantly pulling the helicopter down toward the ground – and generating an upward force called “lift” by rotating its blades through the air. When the force of lift is greater than the force of gravity, the helicopter rises from the ground and flies.
• Ask students if a helicopter might fly differently on the Moon or Mars and why. Note: The Moon doesn’t have an atmosphere in which to generate enough lift to fly. Mars has a very thin atmosphere that may be able to support a small helicopter with very fast-moving blades. NASA’s Mars Ingenuity helicopter will test whether this is feasible.

• Have students cut along the dashed lines of the helicopter template.
• Have students fold the propeller blades, A and B, in opposite directions along the solid lines. The X and Y panels fold toward the center, and Z is folded upward to give the body of the helicopter rigidity and lower its center of gravity for more stable flight.
• Have students do a test flight by standing up, holding the helicopter by its body, raising it as high in the air as they can and dropping it. Ask them: What do you observe? Which way do the blades turn? Drop the helicopter from a higher spot. (Climb a few stairs or stand on a step stool.) How does the performance change?
• Ask students what they might change about their helicopter to affect its performance. Encourage them to make one change to their helicopter and do another drop. If students have a hard time thinking of changes, suggest they try making one more fold on the bottom of their helicopter, or try shortening or changing the shape of the blades. How does the performance change? Why does the chosen change have this effect? Have students share their changes and results.
• Ask students if they can figure out how to make their blades turn faster or slower. Ask them to figure out how to make their blades turn in the opposite direction.
• Ask students to think about how they might improve the performance of their helicopter and make another one that is different from their first. Have them use a different kind of paper or make a much smaller or much larger one. How big of a helicopter can you make that will still work? How small of a helicopter can you make? How do helicopters with different blade sizes compare in performance? What size works best? How do you define "best performance"?
• Ask students what happens to the helicopter when they drop it from higher locations. Most students should say that the blades rotate more.
• Ask students to drop one of their helicopters and try to count how many times the blades rotate. It’s impossible! Ask how they might solve the problem of counting rotations. Older students may have smartphones and be able to record a slow-motion video. Younger students may be stumped by the challenge.
• Have students with access to a slow-motion video proceed in that direction. Have other students attach a straight ribbon to the bottom of their helicopter, stand on the end of the ribbon to hold it securely in place on the floor and drop their helicopter as before. Once the helicopter comes to rest on the ground, have them count the twists in the ribbon to determine how many rotations their helicopter made.
• Have students design an experiment that will allow them to predict the number of spins their helicopter will accomplish from an unknown height. Ask students to measure several heights to drop from, using a measuring tape or nonstandard unit of measurement. Have them start dropping from the lowest point possible – usually about two feet from the ground – and recording the number of turns. Have them make a t-chart to record the distance they dropped from and the number of turns.
• Have students repeat measurements for a variety of heights that they can easily reach.
• Have students graph their results on an x-y plane.
• Have students add the height of a step stool or stairs to the height they can reach and use their graph to estimate the number of turns their helicopter will achieve on a drop from that height. Have older students develop a rule for computing the number of turns from a given height.
• After they’ve recorded their estimate, have students get on the step stool or stairs and drop their helicopter. They will need a peer or family member to hold the bottom of the ribbon steady on the floor.
