The rubber band-powered helicopter is simple to build, and with a little skill, it can fly upwards of 20 feet into the air!
The way it works is as follows: 1. By twisting the propeller, energy is stored in the sport rubber.
2. When the rubber band is flown, it swiftly releases its energy by unwinding, which causes both the propeller blade and the paper cutout to rotate. 3.
3. The paper cutout pulls against the surrounding air, causing horizontal air resistance, also known as drag, to be created. This makes it more difficult for the cutout to rotate. Because the cutout does not spin as readily as the propeller, more energy from the rubber band is released into the propeller, which is much simpler to turn as a result of the reduced spin of the cutout. As a result, the paper mimics the function of the back rotor of a real helicopter.
4. Because of the quick rotation of the propeller, it begins to generate lift by pushing air downward. The helicopter will fly in the direction in which it is pointed if it has enough energy to do so.
