Side rotor for helicopter - works with propeller thrust direction forwards and is fitted to height tailplane peak of rotor blade offset side before or behind height tailplane

摘要

The propeller used is a normal adjustment type without or with a device for blade inward or outward movement. The helicopter tail outrigger (2) is very asymmetrical in its shape, and the height control tailplane is likewise asymmetrical with a large V-installation angle. The installation angle (3) of the thrust propeller is turned laterally and upwards through 6-10 deg. The side rotor is controllable monocyclically or fully cyclically. The effective rotor adjustment angle of the main rotor when flying horizontally at the highest speed through propulsion unloading is reducible by at least one fifth. USE/ADVANTAGE - For fast flying helicopters in which the side rotor acts as an adjustment propeller.
