The invention provides a composite propeller and a driving method thereof, and belongs to the field of power propulsion. The composite propeller comprises a main propeller, a plurality of auxiliary propellers and a revolute pair. The auxiliary propellers are distributed around the main propeller, the auxiliary propellers are connected with the main propeller through revolute pairs, the main propeller can drive the auxiliary propellers to revolve when rotating around the main propeller, and the auxiliary propellers can rotate while revolving. The invention further provides a driving method of the composite propeller, the moments in opposite directions are provided by driving the powered revolute pair and act on the main propeller and the auxiliary propeller respectively, and therefore the main propeller and the auxiliary propeller rotate relatively. The composite propeller concept provided by the invention provides a new choice for the design of the propeller.

    本发明提供了一种复合螺旋桨及其驱动方法,属于动力推进领域。复合螺旋桨,包括主桨、若干个副桨和转动副。所述副桨分布在主桨周围,所述副桨与主桨之间通过转动副连接,所述主桨在绕自身转动时会带动副桨公转,所述副桨在公转的同时可以自转。本发明同时还提供了复合螺旋桨的驱动方法,通过驱动有动力转动副,提供方向相反的力矩,分别作用在主桨和副桨上,从而使主桨与副桨发生相对转动。本发明提出的复合螺旋桨概念,为螺旋桨的设计提供了一种新的选择。
