The invention provides an unlocking control circuit for a steering engine and a steering lock of an aircraft (such as a missile and an unmanned aerial vehicle). The circuit provided by the invention is suitable for aircrafts with steering engine locking torque requirements. The circuit comprises a rudder lock voltage acquisition circuit, an external instruction receiving circuit, a logical operation circuit, an isolation DC/DC and control end circuit thereof, and a multi-energy automatic identification circuit. According to the characteristics of an aircraft energy system, a steering engine control power supply and a power supply are fully utilized, and a steering engine steering lock unlocking and unlocking state maintaining circuit is designed: when a steering engine is in a working state, a steering lock adopts the power supply to realize steering engine unlocking, so that the working reliability of the steering lock is improved, and an aircraft accident caused by failure of the steering lock is avoided; when the steering engine is in the test state, the steering engine enables the rudder lock to be unlocked due to the test requirement, a low-voltage unlocking circuit needs to be designed, and the unlocking requirement of a user is met.

    本发明提供了一种飞行器(如导弹、无人机等)舵机舵锁解锁控制电路。本发明电路适用于带舵机锁止力矩要求的飞行器。本发明电路包含舵锁电压采集电路,外部指令接收电路,逻辑运算电路,隔离DC/DC及其控制端电路,多能源自动识别电路。本发明根据飞行器能源系统特点,充分利用舵机控制电源和功率电源,设计舵机舵锁解锁和维持解锁状态电路:舵机在工作状态时,舵锁采用功率电源实现舵机解锁,提高舵锁工作可靠性,避免因舵锁失效导致飞行器发生意外;舵机处于测试状态时,舵机因测试需要使舵锁解除锁止状态,需要设计低压解锁电路,满足用户解锁需求。
