Our goal was to make the glider fly for 20 feet. But, we didn't reach it successfully. Our fuselage was to heavy in the front which made angle of attack go down. We failed at showing newton's 3rd law. For every action there is an opposite re-action. We achieved at showing Bernoulli's principle because when we threw the glider it stayed in the air since the pressure in the top of the wings decreased. We used flaps to help the glider to provide more lift. The wing thickness was bigger than other peoples that we saw. It helped the glider have more control where the wind wanted to go. When we sanded our airfoil we thought we should make it thinner so that it would have less weight. It was very useful when we flew our glider.
One modification that we did was add flaps to the wings. We did this because it helped the glider fly farther than it did before we added the flaps. Another modification we did was add clay to the front of the fuselage. The clay helped by adding more weight, so that the whole glider would be even on both sides.
We held the bottom of the fuselage so we would have more control to fly. It usually went down because when we had tested it outside in the wind it went up. To fly it, we held the glider upwards and we didn't throw it hard. This caused it to fly more smoothly but, it did the opposite when we tested it. We kept on having to adding clay for the balance of both sides.
