Flight - Aerodynamics

Aim: To look at the 4 main forces of flying and how these can be overcome.

Hypothesis: I think that.......

Method: Working in pairs you are going to make a paper wing and experiment with it.

1. Make a paper wing out of A4 paper 
2. On the field you will need to record and observe how 5 different changes affect the way it flies.

Plane type	How does it behave?	Time ( secs)
Paper sheet, drop	It wobbles to the ground.	1s 45ms
Paper with fold down middle, drop	It was wobble and spinning to the ground.	1s 71ms
Paper with fold and 1 paper clip, drop	It floated to the ground.	1s 95ms
Fold, 2 clips, rudder, drop	It swayed until it touched the ground.	1s  69ms
Fold, 2 clips, rudder throw	It floated and swayed until it crash to the ground.	3s 20ms

Findings:

• With unfolded paper it took 1s 45ms to drop to the ground.
• With a fold through the middle it took 1s 71ms to drop to the ground.
• With the fold through the middle and a little fold at the top with a paper clip it took 1s 95ms. 
• With the fold through the middle and 4 more little folds at the top and 1 fold on each side with an extra paper clip it took 1s 69ms.
• With the fold through the middle and 4 more little folds at the top and 1 fold on each side with an extra paper clip it took 3s 20ms the fly.
