The invention discloses a folding propeller capable of bearing high-speed windblast, comprising a power motor, a propeller hub, an adapter bracket, a limiter, a reed, a centrifugal force lock, a lockshaft, a propeller root shaft, a propeller root, propeller blades, steel balls, a spiral spring, a jack screw and a fairing cap. Under a condition that an unmanned aerial vehicle is at a high speed and a propeller power system does not work, it is guaranteed that the propeller is in a folded state, the unmanned aerial vehicle has such that the unmanned aerial vehicle has a smooth appearance; and the propeller blades in the folded state cannot be unfolded under action of high-speed airflow; in addition, when the propeller power system starts to work, the propeller blades can be smoothly openedonly through rotation of the propeller power motor and are in a working state. According to the invention, the problems of folding storage and unfolding work of the blades of the propeller power system of the unmanned aerial vehicle are solved, such that the blades can bear high-speed windblast in a folding state and can be converted into an unfolding state to work normally.

    一种可承受高速气流吹袭的折叠螺旋桨,包括:动力电机、桨毂、转接支架、限位器、簧片、离心力锁、锁轴、桨根轴、桨根、桨叶、钢珠、螺旋弹簧、顶丝、整流罩。无人机在高速而螺旋桨动力系统未工作的情况下,保障螺旋桨呈折叠状态,使得无人机具有较为顺滑的外形,在高速气流作用下,折叠状态的螺旋桨桨叶不会出现张开情况;另外螺旋桨动力系统开始工作时,桨叶能够仅通过螺旋桨动力电机旋转而顺利张开,呈工作状态。本发明解决的是无人机螺旋桨动力系统的桨叶折叠收纳和展开工作的问题,折叠状态能够承受高速气流吹袭,并能够向展开状态转换,展开状态能正常工作。
