The invention provides a propeller, a power assembly and an aircraft. The propeller comprises a propeller hub (20) and at least two blades (10) arranged in the circumferential direction of the propeller hub (20) at equal intervals. Wherein the propeller blades (10) are rotatably connected with the propeller hub (20) through a rotating shaft (104) so as to fold the propeller blades (10) towards therotating axis of the propeller hub (20) or unfold the propeller blades (10) away from the rotating axis of the propeller hub (20), and a preset included angle is formed between the axis of the rotating shaft (104) and the rotating axis; the propeller hub (20) is used for being in transmission connection with a driving device so as to drive the propeller hub (20) to rotate around the rotating axis. After the aircraft lands on the ground, the blades (10) are rotated about the axis of rotation (104), folding the blades (10) towards the axis of rotation of the hub (20). According to the aircraftwith the propeller, the propeller blades are effectively prevented from scratching the ground or objects on the ground by folding the propeller blades, so that the propeller blades are prevented frombeing damaged.
提供了一种螺旋桨、动力组件及飞行器。其中螺旋桨包括:桨毂(20)以及沿桨毂(20)的周向等间隔设置的至少两个桨叶(10);桨叶(10)通过转动轴(104)与桨毂(20)转动连接,以向桨毂(20)的旋转轴线折叠桨叶(10)或向远离桨毂(20)的旋转轴线展开桨叶(10),并且转动轴(104)的轴线与旋转轴线之间具有预设夹角;桨毂(20)用于与驱动装置传动连接,以驱动桨毂(20)绕旋转轴线转动;在飞行器降落到地面上之后,桨叶(10)绕转动轴(104)转动,使桨叶(10)向桨毂(20)的旋转轴线折叠。具有这种螺旋桨的飞行器通过折叠桨叶有效避免桨叶与地面或者地面上的物体剐蹭,以免桨叶损坏。
