TEAM MEMBERS ：Sapphire Charlotte Allison
Flying paper airplanes used to be the fun we had in our childhood.
There are four forces, thrust, lift, weight and drag, acting on a paper airplane in flight .People should choose suitable paper before they make a paper airplane. To make a good paper airplane, you should select a piece of smooth, hard texture and light weight paper.
1.The paper plane should fly 50ft. from the point of reference.
2.It should be strong, durable.
3.Not only high quality ,but also a good appearence
SHARIDAN:A short nose plane and a huge fuseage.And fold many times in order to gain the weight of nose.Because I think that it could increase the inertia of plane.
SAPPHIRE: In my view, the nose of the plane should has a little weight so that it will let the plane fly steadily. Besides, the wings of the paper plane should be wide and this can make the plane gliding better than other planes.
ALLISON: The centre of the gravity should be towards the front to prevent the plane.
CHARLOTTE ：In my view, the nose of the plane should has little weight to let the plane fly smoothly. Besides, the wings of the plane will not be too big or too small so that it will not increase too much weight or reduce the lift force when the plane is flying.
OLIVER: As for me, the simple plane can also be better than the complex one. on the one side, it can keep the balance when we throw it to the sky; on the another side, this plane can also fly higher by wind action. The only defect thing for this plane is in the collar by the environment.
The best score out of the door: 8~10m about 3.5s
The best score indoor:10~11m about 4s.
Too heavy nose
Test result:(average most of the time)
5~6m . 1second
4~6m. 1 second
The first step :
Choose an A4 paper and fold the paper into half.
The magic of a paper
The second step:
Expand the paper & fold the two corners to the middle in order to make it form an isosceles right triangle.
The third step:
Fold the tip of the paper up to 1 inch.
The fourth step:
Fold both sides of the paper.
The fifth step:
Fold the paper as the center fold line and fold the wings out.
The last step:
Check out whether the wings are flush and symmetric or not.
Test result ：
1. The paper airplanes need a stable structure and appropriate proportion.
2.The gestural movement and the throwing method is the very important thing. 1)Different paper plane has the different angle
2)Control the force to the plane, use skill and method to throw it.
3.In order to keep two sides fo weight and angel balance the step of fold need to be very careful.
4.The proportion of the chord and wingspan should be coordinate so that the paper airplane could be stabilized.
5. Stick double sided adhesive in the middle of the plane to reduce the air resistance when the pane is flying.
Sharidan:The paper plane need a stable structure and appropriate proportion.For example,people gain the weight of nose in order to reduce the resistance and increase inertia.Besides, a huge wings are neccessary to a paper plane .Because wings could make a strong lift force that it makes plane countine flying.
Oliver: 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, and the aerodynamic forces co-interact, creating turbulence that amplifies small changes in the surface of the paper aircraft, That can make the plane wonderful.
Allison: The fuselage wing flap at the back can help to make the airflow pass through a larger angle, in order to increase the flying height. The centre of gravity should be towards the front to prevent the plane from stalling. Making a long and pointed nose is a mistake. it will make the paper airplane under the lack of stability.
Charlotte: Do not break the symmetry of both sides of the planes when you are folding. If the wings are asymmetric, the aircraft will be easy to turn a corner and cannot fly very far. The right suitable proportion of the wings and fuselage are basing on the shape and the texture of the paper. Try a few times will be able to find the best proportion. Pay attention to the balance. By adjusting the shape of the paper plane, or with a note or tape to be properly loaded (if allowed) can regulate the balance of the aircraft.
Sharidan:The paper pla
