Glider Construction

We made gliders with foam, glue, and tape. We could add washers for weight, but it was pretty hard. We had limited time and materials. After constructing it, we were to fly it outside to for hangtime, accuracy, distance, and safe landing. We only had 10 trials for testing. Our glider had large wings for lift, so we didn't have too much drag. We added a washer for weight so it would be more stable. The airfoil had a large angle of attack, camber, and surface area. The tail controlled pitch, yaw, roll, and had an elevator. While constructing our airfoils, we kept Bernoulli's Principle and Newton's 3rd law of motion. After we defined the problem, we used our brains to think of good designs for airfoils that would generate lots of lift and little drag for the best glider. We narrowed down our glider some and added a washer for weight because it kept flipping over in mid air.

Results of Flight:
Hang Time Average: 1.34 seconds
Distance Average: 16.4 ft.
Safe Landing: 70%
Accuracy: 60%

My self evaluation is 12/12
