According to the diagonal rotor tilting type multi-rotor aircraft, the bottom of a fuselage main body is connected with an undercarriage, a middle large rotor and a middle large motor, and the undercarriage, the middle large rotor and the middle large motor are sequentially connected to the top of a middle small tower; the right front part, the left front part, the left rear part and the right rear part of the fuselage main body are correspondingly connected with a right front vehicle arm and a right front power assembly, a left front vehicle arm and a left front power assembly, a left rear vehicle arm and a left rear power assembly, and a right rear vehicle arm and a right rear power assembly; wherein the rotating surfaces of the two small rotors at one diagonal are horizontal, the rotating surfaces of the two small rotors at the other diagonal are inclined around the axes of respective arms, the included angle alpha is formed between the rotating surfaces and the horizontal plane, the sum of the component torques of the lift forces of the two small rotors on the horizontal plane balances the reaction torque of the middle large rotor, and the middle large rotor provides most lift forces. The overall loss of motor power is reduced, the fuel engine replaces a middle large motor to form a fuel-electric hybrid mode, the endurance time is long, the load is large, the wind resistance is high, and the unmanned aerial vehicle becomes a universal flying platform.
一种对角旋翼倾斜式多旋翼飞行器,机身主体底部连接起落架,中部大旋翼、中部大电机,顺序连接在中部小塔的顶部,机身主体右前部、左前部、左后部、右后部对应连接右前机臂和右前动力总成、左前机臂和左前动力总成、左后机臂和左后动力总成、右后机臂和右后动力总成,四个小旋翼的旋转中心的连线是正方形或长方形,其中一个对角的两个小旋翼的旋转面水平,另一个对角的两个小旋翼的旋转面绕各自机臂轴线倾斜,与水平面的夹角ɑ,两个小旋翼的升力在水平面的分力矩总和平衡中部大旋翼的反扭矩,中部大旋翼提供大部分升力,减少电机功率总体损耗,燃油发动机替代中部大电机构成油电混合模式,续航时间长、载重大、抗风能力强、成为通用的飞行平台。
