Periodic variable pitch control system

The utility model discloses a periodic variable pitch control system. The present utility model relates to a thrust-generating rotor assembly (10, 11) based on torque and operating in resonance, the utility model relates to a control device for controlling the tilting moment of a longitudinal rotor blade axis (15) about one or more rotor blades (12a, 12b) in order to control the pitch angle of therotor blades (12a, 12b) and thereby also the horizontal movement of a helicopter or rotorcraft. The rotor torque assembly (10) of the rotor assemblies (10, 11) is also adapted to resonate to providea resonant gain that affects a rotational offset with respect to a torque change generated by the electric machine. 一种周期性变桨控制系统，其被包括在基于扭矩且谐振运行的推力发生旋翼总成(10、11)中，用于控制围绕一个或多个旋翼叶片(12a、12b)的纵向旋翼叶片轴线(15)的倾斜力矩，以便控制这些旋翼叶片(12a、12b)的桨距角并从而还控制直升机或旋翼机的水平运动。旋翼总成(10、11)的旋翼扭矩总成(10)还被调整为谐振运行，从而提供影响关于电机所产生的扭矩改变的旋转偏移的谐振增益。
