The invention discloses a variable pitch propeller, relates to the technical field of aviation, and aims to solve the problem of low aerodynamic performance of the propeller caused by insufficient rotating speed of the propeller. The variable pitch propeller comprises a propeller hub, propeller blades, a push rod and a push disc arranged in the propeller hub, the push rod is used for being connected with the driving mechanism, the push rod penetrates through the propeller hub to be fixedly connected with the push disc, and the driving mechanism is used for controlling the push disc to ascend and descend by driving the push rod. The variable pitch propeller further comprises rotary connecting pieces which are rotatably arranged on the peripheral side of the propeller hub, the propeller roots of the propeller blades are connected with the outer side faces, facing the propeller hub, of the rotary connecting pieces, and the surfaces, deviating from the propeller roots, of the rotary connecting pieces are connected with the push disc. The variable pitch propeller provided by the invention is used in the aircraft.
本发明公开一种变距螺旋桨,涉及航空技术领域,以解决螺旋桨的转速不足导致螺旋桨自身的气动性能低的问题。所述变距螺旋桨包括:桨毂、桨叶、推杆以及设在桨毂内的推盘,推杆用于与驱动机构连接,推杆穿过桨毂与推盘固定连接,驱动机构用于通过驱动推杆控制推盘升降;变距螺旋桨还包括转动连接件,转动连接件可转动的设在桨毂的周侧,桨叶的桨根与转动连接件朝向桨毂的外侧面连接,转动连接件背离桨根的表面与推盘连接。本发明提供的变距螺旋桨用于飞行器中。
