Up, Up, and Away

Have you ever wondered how airplanes and helicopters -- tons of metal -- seem to effortlessly lift into the air and fly like a bird? It's not magic, it's science and technology. The activity in which you are about to participate will help you understand how wing and rotor designs produce the forces necessary to allow airplanes and helicopters to fly. The activity will also allow you to build a rotor, gather data about its flight, and analyze its performance.

Your Task: Build, test, and evaluate a model helicopter rotor based on the design given to you by your teacher.

Provide the Following Data:

1. What is the mass of your rotor and shaft?
_________ grams.

2. What is the velocity of the air coming off the spinning rotor?
Deflection Number ______.

3. What is the average (estimated) altitude your rotor reached?
___________ meters.
