Torque balanced, lift rotor module providing increased lift with few or no moving parts

摘要

A device and method are disclosed for continuous torque/anti-torque force balance, except for trim adjustments. The torque requirements of a single lift rotor are balanced while lifting varying load weights and with varying power settings. A single lift rotor plane of rotation is parallel to and just below the flared air entry end of a relatively short, cylindrical, vertical duct. The lift rotor is closely contained by the duct's inside diameter, and just above a fixed-pitch, essentially vertical, array of air foil shaped vanes. In this configuration, lateral lift in an anti-torque rotational direction is generated, in direct proportion to the lift rotor torque requirements by the forced interaction of the vanes with the swirl air flow component of the lift rotor's rotor wash.

主权项

1. A device for continuous torque/anti-torque force balance of an aerial vehicle or lifting device comprising:
a) a relatively short, cylindrical, vertical duct having a flared at the top air entry end and a bottom air exit end; b) a fixed-pitch, essentially vertical array of air foil shaped vanes, each vane having an outside end, an inside end, a leading edge and a trailing edge, the outside end is attached to the relatively short, cylindrical, vertical duct's inside diameter trailing edge ending at or near the bottom air exit end of the duct; and c) The inside end attached to a Control mount; wherein the leading edge of the air foil shaped vanes points upward toward the duct's flared at the top air entry end.
