The invention discloses a dual-redundancy electric folding and unfolding method and device for an undercarriage. The method comprises the steps that a to-be-executed instruction is determined according to all selected instructions from a flight control system; if it is determined that the to-be-executed instruction is a main retracting instruction and the work triggering condition comprises the main retracting instruction, the main retracting instruction is sent to a main folding and unfolding actuator, so that the main folding and unfolding actuator retracts the undercarriage; if it is determined that the to-be-executed instruction is a main put-down instruction and the work triggering condition comprises the main put-down instruction, the main put-down instruction is sent to the main folding and unfolding actuator to enable the main folding and unfolding actuator to put down the undercarriage; and if it is determined that the to-be-executed instruction is a standby put-down instruction and the work triggering condition comprises the standby put-down instruction, the standby put-down instruction is sent to the standby folding and unfolding actuator, so that the standby folding andunfolding actuator puts down the undercarriage. According to the scheme, the safety and reliability of the undercarriage system can be improved.

    本发明公开了一种起落架的双余度电动收放方法及装置,该方法包括:根据来自所述飞控系统的各个选定指令确定待执行指令;若确定所述待执行指令是主收起指令且工作触发条件包括主收起指令,则向所述主收放作动器发送主收起指令,以使所述主收放作动器收起所述起落架;若确定所述待执行指令是主放下指令且工作触发条件包括主放下指令,则向所述主收放作动器发送主放下指令,以使所述主收放作动器放下所述起落架;若确定所述待执行指令是备放下指令且工作触发条件包括备放下指令,则向所述备收放作动器发送备放下指令,以使所述备收放作动器放下所述起落架。该方案可以增加起落架系统的安全可靠性。
