The invention provides an electric rotorcraft. The electric rotorcraft is characterized in that the electric rotorcraft comprises a rack, a propeller motor, a pre-rotating motor and a battery pack, arotor disc is arranged at the top of the rack, a rotor wing is mounted at the top of the rotor disc, the pre-rotating motor for assisting a rotor wing to rotate is arranged on the rotor disc, the propeller motor is arranged in the middle of the rack, propellers are installed on the propeller motor, an empennage is arranged at the rear end of the bottom of the rack, the battery pack is arranged inthe center of the bottom of the rack, and the propeller motor and the pre-rotating motor are both electrically connected with the battery pack. Compared with electric rotorcrafts in the prior art, theelectric rotorcraft of the invention, taking electric power as power to drive the propellers, making the motor drive rear wheels to assist in sliding and pushing to assist in flying and using the motor as power to assist pre-rotating blades, obtains initial lifting force, is separated from the ground as soon as possible to lift off, has the advantages of small size, light weight, low environmentrequirement during takeoff, simplicity in operation, and high safety, and meets the green and environment-friendly requirements.

    本发明提出了一种电动旋翼机,其特征在于:包括机架、螺旋桨电动机、预旋电机和电池包,所述机架的顶部设有旋翼盘,所述旋翼盘的顶部安装有旋翼,所述旋翼盘上设有辅助所述旋翼转动的预旋电机,所述机架的中部设有螺旋桨电动机,所述螺旋桨电动机上安装有螺旋桨,所述机架的底部后端设有尾翼,所述机架的底部中央设有电池包,所述螺旋桨电动机和预旋电机均与所述电池包电性连接。与现有技术相比,以电力为动力驱动螺旋桨;以电动机驱动后轮作为辅助滑跑推动助飞的方式;用电动机为动力辅助预旋旋翼片,使得旋翼机得到初始升力,尽快脱离地面而升空;具有体积小、重量轻、起飞时对环境要求低,操作轻便,安全性高,并且符合绿色环保要求。
