1Q40.05 Helicopter Model

This demonstration simulates what happens when a helicoper takes off. A fan starts turning. The device has acquired angular momentum using an internal power supply. To compensate the entire device starts spinning in opposite direction. If you tilt the fan you can show how a helicopter moves foward also.

Picture: Not Yet Available

 

Setup Requirements: Assembled as needed. Batteries may need to be recharged or replaced. Ask for at least one day in advance.

 

Equations: Conservation of angular momentum

 

Safety Issues: Being cut by fan blade
