The invention relates to the technical field of vehicles, in particular to a rotorcraft with backward inclined power rotors, which comprises a rotorcraft body and the power rotors arranged on the rotorcraft body, a rotating shaft of each power rotor is arranged in a rear chamfer, namely, a rotating plane of a rotor blade of each power rotor is inclined backwards, so that when the rotorcraft moves forwards, the rotor blade of each power rotor is inclined backwards, and the rotor blade of each power rotor is inclined backwards. The included angle between the air flow coming from the front and the air flow pressed down by the power rotors is an obtuse angle, a large part of the air flow counteracts the air flow, namely the air flow is greatly reduced, the effect similar to the ground effect is generated, according to the energy balance principle, most of the energy of the power rotors is converted into lift force, little loss is caused by the air flow, and the utilization rate of the air flow is greatly increased; the backward inclination angle of the power rotor wings is not large, the wind resistance of the whole machine is small, and the cruising speed is high.

    本发明涉及交通工具技术领域,具体指一种带后倾斜动力旋翼的类旋翼机,包括机体和设于机体上的动力旋翼,所述动力旋翼的旋转轴呈后倒角设置,也即是说动力旋翼的旋翼片所旋转的平面向后倾斜,这样设置,当旋翼机向前运动时,前方来的空气流和动力旋翼下压空气流夹角为钝角,有很大一部分空气流抵消,也即空气流动大大减少,产生了类似地效的效果,根据能量守衡原理,动力旋翼能量大部分转化为升力,而极少因为空气流动而损耗,极大地提高了空气流利用率;且动力旋翼向后倾斜角度不大,整机风阻小,巡航速度快。
