초록

A cycloidal rotor system having airfoil blades travelling along a generally non-circular, elongated and, in most embodiments, dynamically variable orbit. Such non-circular orbit provides a greater period in each revolution and an optimized relative wind along the trajectory for each blade to efficiently maximize lift when orbits are elongated horizontally, or thrust/propulsion when orbits are vertically elongated. Most embodiments, in addition to having the computer system controlled actuators to dynamically vary the blade trajectory and the angle of att...

청구항

1. A cydoidal rotor having a plurality of airfoil blades mounted for orbiting about the rotor's axis of rotation; blade supporting means operative to position the blades to follow a generally non-circular trajectory about said axis of rotation; counterbalancing means for keeping the rotor balanced as the blades' radial positions change; blade pitch adjusting means for adjusting the blades angle-of-attack; and drive means for propelling the blades along said trajectory. 2. The cydoidal rotor of claim 1, inducing actuator means for positioning the blades r...
