A two-arm sweepback multi-rotor aircraft is characterized in that a left arm and a right arm are connected to the left side and the right side of the head of a fuselage in a sweepback manner, and a right front end upper motor, a right front end upper propeller, a right middle section upper motor, a right middle section upper propeller, a right middle section lower motor, a right middle section lower propeller, a right rear end upper motor and a right rear end upper propeller are sequentially connected to the right arm; the left front end upper motor, the left front end upper propeller, the left middle section upper motor, the left middle section upper propeller, the left middle section lower motor, the left middle section lower propeller, the left rear tail end upper motor and the left rear tail end upper propeller are sequentially connected to the left vehicle arm. The projection distance of the tip distance of two adjacent propellers on the right arm and the left arm on the horizontal axis of the fuselage is B, B is larger than or equal to 0.05 r, r is the radius of the propellers, downwash flows of the right front end upper propeller, the left front end upper propeller, the right rear end upper propeller and the left rear end upper propeller do not interfere with one another, the wide propeller layout is suitable for pesticide spraying operation, and the efficiency is improved. The method can also be applied to transportation, measurement, exploration and other fields.

    一种两臂后掠多旋翼飞行器,机身的头部左右两边后掠地连接左机臂和右机臂,右前端上电机、右前端上螺旋桨、右中段上电机、右中段上螺旋桨、右中段下电机、右中段下螺旋桨、右后末端上电机、右后末端上螺旋桨依次连接在右机臂上;左前端上电机、左前端上螺旋桨、左中段上电机、左中段上螺旋桨、左中段下电机、左中段下螺旋桨、左后末端上电机、左后末端上螺旋桨依次连接在左机臂上;右机臂、左机臂上相邻两个螺旋桨的尖距离在机身横轴的投影距离B,B≥0.05r,r是螺旋桨的半径,右前端上螺旋桨、左前端上螺旋桨、右后末端上螺旋桨、左后末端上螺旋桨的下洗气流没有相互干扰,宽幅的螺旋桨布局适合农药喷洒作业提高效率,也可应用于运输,测量,勘探等领域。
