Rotor system for rotary wing aircraft has part of rotor designed, suspended or connected to react to resulting change of rotation value with movement relative to or additional to original rotation which influences aerodynamic forces

摘要

The rotor system with at least one rotor (4) has a facility whereby a rotation around a rotor axis can cyclically accelerate or vary for control. At least one part (20,30) of the rotor is designed, suspended or connected so that it reacts to the resulting change of a rotation value with a movement relative to or additional to its original rotation around the rotor axis which influences the aerodynamic forces. The aforesaid part of the rotor is an air force influencing device designed so that it reacts to cyclic changes of rotational force or speed transmitted to the rotor. Independent claims are also included for the following: (A) a construction or retrofit kit for a rotor system; (B) a rotary wing aircraft with the proposed rotor system; and (C) a method for the control of a rotary wing aircraft in which a rotation value relating to the rotation of the rotor is cyclically varied or modulated as a function of a control signal.
