The invention discloses a high-speed coaxial unmanned helicopter additionally provided with double tail propellers, which comprises a main helicopter body and the tail propellers, the main helicopter body is provided with coaxial double rotors, and a course control system adopting a semi-differential control mode is adopted; the tail propellers are mounted on two sides of the tail part of the main helicopter body and are symmetrically distributed; the tail propellers do not work when an unmanned helicopter is in a hovering state, and when the unmanned helicopter is transited to a high-speed flight state from a low-speed flight state, the tail propellers gradually participate in work and provide thrust. The structure of an existing coaxial double-rotor unmanned helicopter is improved, and the double tail propellers are additionally arranged, so that the rotor consumption power is reduced, and the flight speed of the coaxial double-rotor unmanned helicopter is increased.

    本发明公开了一种加装双尾推的高速共轴无人直升机,包括主机身以及尾推,主机身上设有共轴双旋翼,且采用半差动操纵方式的航向操纵系统;尾推安装在主机身的尾部两侧,呈对称式分布;尾推在无人直升机悬停状态下不工作,当无人直升机从低速过渡到高速飞行状态时,尾推逐渐参与工作,提供推力。本发明通过改善现有共轴双旋翼直升机的结构,加装双尾推,降低了旋翼消耗功率,提高共轴双旋翼无人直升机的飞行速度。
