Paper plane are a class of model plane, the force that make a paper plane to fly are the same ones that apply to real airplanes. However, their construction material produces a number of dissimilar effects on flight performance.
In general, there are four aerodynamic forces that act on the paper aircraft while it is in flight:
Thrust, which keeps the plane moving forward;
Aerodynamic lift, acting on horizontal surface areas that lifts the plane upward;
Gravity, which counteracts lift and pulls the plane downward; and
Air drag, which counteracts thrust and reduces the plane's forward speed.
Altogether, the aerodynamic forces co-interact, creating turbulence that amplifies small changes in the surface of the paper aircraft. Modifications can be made to most paper airplanes by bending, curving or making small cuts in the trailing edges of wings and in the airplane's tail, if it has one.
We would like to make a kind of paper plane which is simple but strong, small but potent.
Statement of the Problem:
Design and build a strong and durable paper plane that can fly 50 ft. And possible to manufacure the design in the classroom.

Research Solution (10pts)
List/sketch possible solutions that might be used in your final design. Clearly identify and describe how each of these ideas relates to the problem statement.
Eric: He made a plane that the head is flat. And make the wings small that can fly far by using super power. But it cannot fly far and high.
Shirley: She made a plane which was made from internet. This can fly father than Eric’s one, but to let the plane father, each step must very accurate or the plane would fly back. And it’s not easy to make.
Zehao: it’s easy to fly high but can’t fly far. The head of plane is sharp that can fly faster than others. And the wings are big that it’s easy to change the direction of the plane according the wind.
Alice: the head of plane is flat that the plane can fly stably. But it’s easy to hit up so that cannot fly far.
These are some of our first ideas. At first we wanted to make some creative ones, so we tried to make some different shapes.
Research and Generating Ideas – See what others have done to solve the problem.
1. Fold a standard paper plane. If you don't know how to make a paper plane, check out the video for the experiment.
2. The plane must be perfectly symmetrical. You might want to use a ruler to make sure your plane has perfect symmetry.
3. Make the creases as sharp and tight as possible.
4. Do not allow the wings, nose, or tail of the plane to become crumpled.
5. Set up the two fans so that they face each other and are roughly two feet apart.
6. Turn the fans on to their lowest setting and make sure they are blowing directly towards each other.
7. Try setting your paper plane in the exact middle of the two fans. A slight deviation from the middle may cause the plane to fly off course or crash into the ground.
8. You may have to experiment with the distance of the two fans depending on the type and size of your fan.
9. Once you have the fans at the perfect distance, you should be able to set your plane right in the middle and watch it float.
The main reason why paper airplanes look different than real planes is to allow the paper airplane constructor to make a plane as easily and quickly as possible. Adding a tail and any other pieces to a paper airplane would require more folds, and probably scissors, tape and glue. The simplest airplane is the flying wing, and that's what most paper airplanes are.
The tail of a real plane usually also has a vertical tail. The vertical tail acts like the fins of an arrow to keep the nose of the plane pointed in the direction its headed, this is called positive directional stability. The Fuselage (center body of a plane, on paper airplanes its the part you hold for throwing) acts like the vertical stabilizer of real airplanes. Sometimes bending the wingtips up on paper airplanes also helps to add directional stability. The combination of the fuselage and wingtips on paper airplanes allows them to have positive directional stability without a vertical tail.
A long flight occurs when these four forces — drag, gravity, thrust, and lift are balanced. Some planes (like darts) are meant to be thrown with a lot of force. Because darts don't have a lot of drag and lift, they depend on extra thrust to overcome gravity. Long distance fliers are often built with this same design. Planes that are built to spend a long time in the air usually have a lot of lift but little thrust. These planes fly a slow and gentle flight.

Darts are easy to fold schoolyard paper airplanes that the kid in you wants. Easy to fold, easy to fly for almost immediate gratification.

Gliders are floaters and continue to fly over long distances. Gliders fly better in calm environments, best in large indoor spaces if possible.

The development of Zehao planes
Our design process: zehao 1 (model name)can not keep balance during the flight. It may fly as a circle,and fly back to the starting point. After four-time improvement, we got a better-quality plane which is more stable. Zehao 6 may fly upwards. Then came to the zehao 8. We added more weight to the head of the plane to avoid flying upwards so that it can fly in a horizontal line.
3.Test Solution and Evaluate Solutions (5pts)
Distance and time:
1: 9m 2.7s 2: 4m 2s 3:5.8m 2.2s 4: 11m 3s
This paper plane should be based on the direction and strength of the wind that can fly far. Sometimes, this would fly back so that the plane cannot fly far, but the plane is sustainable.
We can have creases on the wings that can make the plane fly sustainable.
1: 6m 2.4s 2: 13m 3.2s 3: 11m 2.81s
It’s sustainable and can fly farther than other panes. In order to fly farther, we need 15 to 25 degrees to fly. But this is also affected by the wind because of the big wings.
We can try to make the wings smaller that reduce the effect of wind on plane.
1: 7m 2.3s 2: 10m 3s 3:6m 2.7s
This plane must use super power to let the plane far and the speed in the sky is quick. We need 35 to 45 degrees to fly it.
We can change the head of plane to be flat that can fly sustainable.
4 Eric 3
1: 14m 2.7s 2: 12m 2.3s 3:16m 3.3s
It dropped down very soon and must use super power to fly. The direction hasn’t changed.
We can let the angle of plane’s head larger that can fly farther.
5 black 2
1: 7m 2.7s 2: 8m 2.5s 3: 11m 3s
The plane can’t fly so far. And it’s easy to fly back.
We should change the head of plane or wings of plane to make sure the plane can fly far.

Communicating processes and results (7pts)
Demonstrate the operation of your Paper plane to the class. As part of your demonstration, describe the steps involved in creating your design.
Make a ppt presentation or a video.l stabilizer of real airplanes. Sometimes bending the wingtips up on paper airplanes also helps to add directional stability. The combination of the fuselage and wingtips on paper airplanes allows them to have positive directional stability without a vertical tail.
