The invention discloses an undercarriage folding control circuit, and belongs to the design field of undercarriage folding control systems in the aviation field. In the landing gear folding control circuit, interlocking of the wheel load switch is added. When aircraft wheels touch the ground (an aircraft landing gear strut is in a compressed state), a loop of the landing gear folding control circuit is disconnected, and even if the landing gear is controlled to be folded, power cannot be supplied to the landing gear folding electromagnetic valve; when the aircraft wheels do not touch the ground (the aircraft landing gear strut is in a released state), the landing gear can be normally retracted. The risk that when aircraft wheels touch the ground, an undercarriage operation switch is mistakenly operated to retract the undercarriage, and an undercarriage retracting and releasing actuating cylinder is used for pressing and retracting the undercarriage, so that the undercarriage conflicts with an undercarriage supporting column mechanical locking device is avoided.

    本发明公开了一种起落架收起控制电路,属于航空领域中的起落架收放控制系统设计领域。本发明在起落架收起控制电路中,增加了轮载开关的联锁。当飞机机轮着地时(飞机起落架支柱处于压缩状态),断开起落架收起控制电路的回路,即使操纵起落架收起,也不会给起落架收起电磁阀供电;当飞机机轮未着地时(飞机起落架支柱处于释放状态),可正常进行起落架的收起。本发明规避了飞机机轮着地时,误操作起落架操作开关进行收起落架、起落架收放作动筒供压收起落架,从而与起落架支柱机械锁定装置冲突的风险。
