The invention relates to the technical field of unmanned aerial vehicles, and particularly discloses an unmanned helicopter for power application. The unmanned helicopter comprises a rack, a power device and a rotor wing assembly installed on the rack. The rotor wing assembly comprises rotor wing blades, each rotor wing blade is formed by alternately connecting a plurality of first rotor wing pieces and a plurality of second rotor wing pieces, and the strength of the first rotor wing pieces is higher than that of the second rotor wing pieces; the power device is installed on the rack, connected with the output end of the rotor wing assembly and used for driving the rotor wing assembly to rotate. By means of the alternate connection arrangement of the first rotor wing pieces and the second rotor wing pieces which are different in strength, normal operation of the rotor wing assembly can be guaranteed, the rotor wing blades can be broken and disengaged at one second rotor wing piece when being damaged by the external environment, and therefore it is guaranteed that the other rotor wing blades can still continue to operate; the situation that the power device is damaged due to the fact that the rotor wing blades are damaged is avoided, and then the service life of the unmanned helicopter is prolonged.

    本发明涉及无人机技术领域,具体公开了一种电力应用无人直升机。该无人直升机包括机架、动力装置和安装于机架上的旋翼组件;旋翼组件包括旋翼叶片,旋翼叶片由多个第一旋翼片和多个第二旋翼片交替连接组成,第一旋翼片的强度高于第二旋翼片;动力装置安装于机架上,动力装置与旋翼组件的输出端连接,动力装置用于驱动旋翼组件旋转。利用强度不同的第一旋翼片与第二旋翼片的交替连接设置,不仅能保证旋翼组件正常运行,还能使旋翼叶片在遭受外部环境破坏时于一个第二旋翼片处断裂并脱离,从而保证其余的旋翼叶片仍能够继续运行,避免了因旋翼叶片破坏而导致动力装置损伤的情况发生,进而延长了无人直升机的使用寿命。
