Abstract:

The rotor force parameters considered were thrust, torque, pitching moment, and normal force, for the simulated flight conditions of hover, takeoff, and landing. The flow parameters investigated included tip vortex trajectories and streamline patterns. Additional studies were made to consider the effects of rotor blade mismatching upon thrust and power requirements of a rotor system. Author
