Method of operating and controlling the deflection angle of a control surface of a hybrid helicopter

摘要

The method involves controlling steering angles of horizontal tail empennages (25-35) by utilizing a horizontal empennage steering angle control and adjusting loop to reduce total power consumed by a main lifting rotor (10) and a pusher propeller (6) in forward direction. Blades or the pusher propeller are controlled by a speed regulation loop. The steering angles of the horizontal tail empennages are not greater than 10 degrees. Power delivered by a driving source after activation of the steering angle control and adjusting loop is determined. Independent claims are also included for the following: (1) a regulation and control system for a rotorcraft (2) a control program having a set of instructions for executing a rotorcraft controlling and regulating method.
