The invention belongs to the field of aircraft power supply design, and particularly relates to an aircraft self-locking power supply system. And by adopting the design that each subsystem is automatically powered on and off along with the aircraft, the control burden is increased. An independent power-on switch is adopted, so that the reliability and the safety of the system are reduced. According to the aircraft self-locking power supply system, a relay 1P and a self-locking unit are connected to a power supply circuit in parallel, the relay 1P is grounded after sequentially passing through a power-on switch and a maintenance switch, the maintenance switch is normally closed, and a switch of the relay 1P is connected into the power supply circuit; the self-locking unit comprises an undercarriage landing switch and a relay 2P which are connected in series, the control low ends of the relay 2P and the relay 1P are grounded after passing through a switch of the relay 2P, and the relay 1P is controlled by a power-on switch. A driver does not need to pay attention to power-on and power-off of a single system and the power-on time sequence of each system, and meanwhile various faults caused by improper power-on time sequence of each system are automatically avoided.

    本发明属于飞行器供电设计领域,具体涉及一种飞行器自锁供电系统。采用各分系统随飞行器自动上下电的设计,增大了操纵负担。采用独立上电开关,降低了系统的可靠性及安全性。本发明飞行器自锁供电系统包括在该供电线路上并列连接有继电器1P和自锁单元,所述继电器1P依次经过上电开关和维护开关后接地,所述维护开关常闭,继电器1P的开关连接在供电线路中;所述自锁单元包括串行连接的起落架落地开关和继电器2P,继电器2P和继电器1P的控制低端共同经过继电器2P的开关后接地,由上电开关控制继电器1P。使驾驶员不必关注单个系统的上下电以及各系统的上电时序,同时也自动规避了由于各系统上电时序不当引发的各类故障。
