The invention discloses a rapid parking circuit of a parachute landing recovery unmanned aerial vehicle. The rapid parking circuit comprises an engine, a generator, a propeller, a brake relay, an airborne power supply connector and an airborne computer connector, the engine is a power source of the unmanned aerial vehicle. The generator is a main power source of the unmanned aerial vehicle. The airborne computer connector is connected with an airborne computer and transmits a brake signal output by the airborne computer to the brake relay; when the coil of the brake relay is not excited, the three-phase alternating current output by the generator is directly input into the airborne power supply connector; when the airborne computer connector transmits a brake signal to the brake relay, the brake relay disconnects the three-phase alternating current output by the generator from the airborne power supply connector, and the three-phase alternating current output by the generator is in mutual short circuit through contact short circuit in the brake relay. The propeller can quickly stop rotating, and therefore the problem that the propeller is twisted into a main parachute rope is solved.

    本发明公开了一种伞降回收无人机快速停车电路,包括发动机、发电机、螺旋桨、制动继电器、机载电源连接器和机载计算机连接器;发动机为无人机的动力源,发电机为无人机的主电源;机载计算机连接器与机载计算机连接,将机载计算机输出的制动信号传输至制动继电器;制动继电器线圈无激励时,发电机输出的三相交流电直接输入到机载电源连接器;当机载计算机连接器将制动信号传输给制动继电器时,制动继电器将发电机输出的三相交流电与机载电源连接器断开,在制动继电器内部通过触点短接将发电机输出的三相交流电相互短接。本发明能够使螺旋桨快速停止旋转,从而克服了螺旋桨绞入主伞伞绳的问题。
