Glider Project - By Jack Middleton and Ben Brinkman
The airfoil uses lift to fly. The weight and gravity act against the lift. The glider flies better with a large surface area, a big camber, and flaps. The lift to drag ratio was around 5 which is a good ratio in order to fly. Bernoulli's Principle says that if the air travels above the wing faster than under the wing the pressure above the wing will decrease creating lift. Newton's 3rd Law of Motion says that if the wing pushes down on the air the air will push back creating lift. The spoilers lift up and slow down the plane to make a safe landing. We used these flight terms to make our glider fly as far as possible.
I modified the glider by making flaps for the wings. Adding flaps increased surface area which increased lift. I also modified the front by making it heavier so it landed front first for a safer landing. The weight on the front made it land with it's nose down facing forward for a safe landing.
To throw the glider well you should start by holding it in the middle and putting your finger at the back to balance the weight. Throw the glider with the front and wings facing a little up to create more lift. Throw it with about half of your strength so it doesn't crash. If you throw it like this it will get maximum lift.
