Hovering Model Helicopter Rotor Testing
Proceedings of the Helicopter Test Methodology - Williamsburg, Virginia 1984, 1984In planning a research investigation of a hovering model rotor, a relatively large test chamber was selected because of the desire to minimize room interference effects. However, initial testing revealed large random variations of thrust, torque, and blade flapping.
