The invention discloses an opening and closing propeller system for a vertical take-off and landing aircraft, and relates to the technical field of aircrafts and aircrafts. The opening and closing propeller system for the vertical take-off and landing aircraft comprises a lift propeller and a thrust propeller which are arranged on the aircraft aircraft, the lift propeller comprises a main driving motor, the output end of the main driving motor is fixedly connected with a center transmission shaft, the upper end of the center transmission shaft is fixedly connected with a fixed propeller, the fixed propeller comprises a fixed propeller hub and a fixed propeller rotor, and the fixed propeller hub is fixedly connected with the center transmission shaft. And the fixed propeller hub is fixed with the upper end of the central transmission shaft. According to the opening and closing propeller system for the vertical take-off and landing aircraft, the rotors with the four-blade propellers are adopted, in the hovering take-off state, the lift force of a single rotor component is increased through the four-blade propellers, and therefore the total number of the lift force rotors is reduced, the total weight of the rotor system is reduced, and the effect of improving the flight performance of the aircraft is achieved; the four-blade rotor wings are subjected to feathering locking, so that the windward area in a cruising state is reduced, and the flight resistance is reduced.

    本发明公开了一种用于垂直起降飞机的开合桨系统,涉及飞行器飞机技术领域。该种用于垂直起降飞机的开合桨系统,包括设置在飞行器飞机上的升力桨和推力桨,所述升力桨包括主驱动电机,且主驱动电机的输出端固定连接有中心传动轴,所述中心传动轴的上端固定连接有定桨,且定桨包括定桨桨毂和定桨旋翼,所述定桨桨毂与中心传动轴的上端固定。该种用于垂直起降飞机的开合桨系统,采用四叶桨的旋翼,在悬停起飞状态时,通过四叶桨提升单个旋翼部件的升力,从而减小升力旋翼的总数量,减小旋翼系统的总重量,起到提升飞行器飞机飞行性能的效果,在巡航状态,通过将四叶旋翼进行顺桨锁止,减小巡航状态下的迎风面积,降低飞行阻力。
