The invention relates to a multi-rotor unmanned aerial vehicle which comprises a vehicle body (201) and a power system installed on the vehicle body (201), the power system comprises a plurality of propellers, and the propellers comprise a front propeller (101) and a rear propeller (102) located behind the front propeller in the flight direction. A first pivot axis (103) of the front propeller inclines towards the front of the fuselage (201) in the flight direction, and/or a second pivot axis (104) of the rear propeller inclines towards the rear of the fuselage (201) in the flight direction, and the first pivot axis and the second pivot axis intersect in space and form an included angle of 1-6 degrees. Through the technical scheme, the multi-rotor unmanned aerial vehicle provided by the invention can offset airflow interference of the front propeller to the rear propeller and rotation speed deviation of the front and rear propellers caused by head-up torque of the propellers, so that the rotation speeds of the front and rear propellers approach to each other, and an available control accelerator is improved.

    本公开涉及一种多旋翼无人机,包括机身(201)和安装在该机身(201)上的动力系统,所述动力系统包括多个螺旋桨,所述螺旋桨包括前螺旋桨(101)和沿飞行方向位于该前螺旋桨后方的后螺旋桨(102),所述前螺旋桨的第一枢转轴线(103)沿所述飞行方向朝向所述机身(201)的前方倾斜,以及/或者所述后螺旋桨第二枢转轴线(104)沿所述飞行方向朝向所述机身(201)的后方倾斜,所述第一枢转轴线与所述第二枢转轴线空间相交并具有1°~6°的夹角。通过上述技术方案,本公开提供的多旋翼无人机能够抵消前螺旋桨对后螺旋桨气流干扰、螺旋桨本身抬头力矩引起的前后螺旋桨转速偏差,使前后螺旋桨转速趋近,提高可用操控油门。
