The invention provides an autorotorcraft rotor prerotation control device and a control method thereof. The control device comprises a prerotation mechanism and a control mechanism, and the prerotation mechanism comprises a belt transmission structure and a tensioning structure; the tensioning structure comprises a belt tensioning rocker arm, a belt tensioning wheel and a belt pressing block, wherein the belt tensioning wheel and the belt pressing block are fixed to the belt tensioning rocker arm, and a belt loosening spring is arranged on the belt tensioning rocker arm. The control mechanism is connected with the belt tensioning rocker arm through a pre-rotation pull wire, when the control mechanism tensions the pre-rotation pull wire, the belt tensioning wheel compresses the belt to enable the belt to be in a tensioning state between the large belt wheel and the small belt wheel, and power of an output shaft of the engine is transmitted to the rotor wing clutch gear through the belt transmission structure and the transmission mechanism. According to the device, a new pre-rotation and control mode is adopted, and a pre-rotation cylinder and a gas circuit control device are removed on the basis of realizing the original pre-rotation control function, so that the complexity and the structural weight of a pre-rotation system are reduced, and the safety and the reliability of the pre-rotation system are improved.

    本发明提供了一种自转旋翼机旋翼预旋操纵装置及其操纵方法,操纵装置包括预旋机构和操纵机构,所述的预旋机构包括带传动结构和张紧结构;张紧结构包括皮带张紧摇臂以及固定在皮带张紧摇臂上的皮带张紧轮与皮带压紧块,皮带张紧摇臂上设置有皮带放松弹簧;所述的操纵机构通过预旋拉线与皮带张紧摇臂连接,操纵机构拉紧预旋拉线时,皮带张紧轮压紧皮带使皮带在大带轮和小带轮之间处于张紧状态,发动机输出轴的动力通过带传动结构和传动机构传递到旋翼离合齿轮。本发明采用新的预旋及其操纵操纵方式在实现原有预旋操纵功能的基础上去掉了预旋气缸及气路控制装置,降低了预旋系统的复杂性和结构重量,提高了其安全性和可靠性。
