The invention discloses an anti-drag propeller and an unmanned aerial vehicle, and belongs to the field of unmanned aerial vehicles. The anti-drag propeller comprises a motor base, a motor, a connecting sleeve, blades and a blade limiting device; the motor is fixedly installed on the motor base, and the connecting sleeve is fixedly connected to an output shaft of the motor; the blades are rotatably connected to the connecting sleeve through a blade shaft, the blade shaft is perpendicular to an output shaft of the motor, and the at least two blades are circumferentially and uniformly arranged by taking the motor as the center; and a paddle limiting device is connected between each blade and the connecting sleeve, the blade limiting device is used for limiting the rotating range of the blades, and two end points of the rotating range of the blades correspond to the blades and are parallel to and perpendicular to the output shaft of the motor respectively. The unmanned aerial vehicle comprises a fuselage and the anti-drag propeller installed on the fuselage. After the anti-drag propeller is applied to an aircraft, the blades can be unfolded to provide thrust when the motor works, can be folded to reduce resistance after the motor is closed, and can be folded to reduce the size during transportation and storage.

    本发明公开了一种减阻螺旋桨及无人机,属于无人机领域。减阻螺旋桨包括电机座、电机、连接套、桨叶和桨叶限位装置;电机固定安装在电机座上,连接套固定连接在电机的输出轴上;桨叶通过桨叶轴可转动地连接在连接套上,桨叶轴垂直于电机的输出轴,桨叶至少有两个且以电机为中心周向均匀布置;每个桨叶与连接套之间均连接有桨叶限位装置,桨叶限位装置用于限制桨叶的转动范围,桨叶的转动范围的两个端点分别对应于桨叶平行于和垂直于电机的输出轴。无人机则包括机身和安装在机身上的减阻螺旋桨。本发明的减阻螺旋桨在应用于飞机上后,桨叶能够在电机工作时张开而提供推力、在电机关闭后收起而减小阻力、在运输和保存时收起而降低尺寸。
