The technical scheme of the invention discloses a propeller and an unmanned aerial vehicle, the propeller comprises blades and feathering blades, and the feathering blades are arranged on the blades and extend along the extension direction of the blades; and when the feathering blade is subjected to the airflow effect, the paddles can rotate, so that the extension direction of the paddles is consistent with the airflow direction. According to the technical scheme, the feathering blades are arranged on the paddles to adjust and stabilize the stalling position of the propeller, so that the extension direction of the paddles is consistent with the airflow direction, the aerodynamic resistance borne by the unmanned aerial vehicle is reduced, and the endurance and course stability of the unmanned aerial vehicle is improved.

    本发明的技术方案公开了一种螺旋桨和无人机,螺旋桨包括桨叶和顺桨片,顺桨片设于桨叶,并沿桨叶的延伸方向延伸;当顺桨片受到气流作用时,桨叶能够转动,使得桨叶的延伸方向与气流方向一致。本发明的技术方案通过在桨叶上设置顺桨片来调整并稳定螺旋桨的停转位置,使得桨叶的延伸方向与气流方向一致,以减少无人机受到的气动阻力,从而提高无人机的航时和航向稳定性。
