The invention relates to the field of helicopters and rotors, and provides a high-lift combined main rotor of a helicopter, which is used for improving the lift of the helicopter and comprises a straight tube section, a main lift body, a main lift body thrust engine, a pull-down steel wire structure, an auxiliary pull-up steel wire structure and an expansion section, and the other end of the rotating part is connected with the main lifting body, and a thrust engine is arranged at the tail part of the main lifting body and pushes the main rotor wings to rotate. According to the large-lift combined main rotor of the helicopter, large lift can be efficiently generated by means of the large linear speed of the far-end wingtip part.
本发明涉及直升机和旋翼领域,提供一种直升机大升力组合主旋翼,用以提高直升机升力,包括直筒段、主升力体、主升力体推力发动机、下拉钢丝结构、辅助上拉钢丝结构、扩展段,所述直筒段的一端固定于中心转轴上,同中心转轴旋转部分一起共同旋转,另一端与主升力体连接,所述主升力体的尾部设有推力发动机,推动主旋翼旋转。本发明直升机大升力组合主旋翼,利用远端翼尖部位的较大线速度,能够高效产生较大升力。
