A helicopter capable of counteracting reaction torque by means of an electric tail rotor comprises a main rotor above a helicopter body, and the tail rotor is driven by a battery, arranged below the main rotor, parallel to the main rotor and opposite to the main rotor in rotation direction. At least one tail rotor wing is arranged; the tail rotor not only can counteract reaction torque generated by the main rotor, but also can provide lift force for the helicopter. Compared with an existing single-rotor-wing helicopter, the single-rotor-wing helicopter is simple in structure and light in weight, the occupied space is reduced, and the safety of the helicopter can be well improved.

    一种依靠电动尾旋翼抵消反扭矩的直升机,包括机身上方的主旋翼,尾旋翼是电池驱动的,在主旋翼的下方、与主旋翼平行,旋转方向相反;尾旋翼至少设有一个;尾旋翼不仅能抵消主旋翼产生的反扭矩,而且还能为直升机提供升力。与现有的单旋翼直升机相比,本发明结构简单、重量轻、减少占地空间,还能很好的提高直升机安全性。
