The invention belongs to the technical field of helicopter engine control systems, and particularly relates to a helicopter multi-engine controller multi-redundancy power distribution circuit and a control method.The circuit comprises a plurality of power supply bus bars and a plurality of power distribution modules, and the power supply bus bars are connected with the input end of each power distribution module; the output end of each power distribution module is connected with a power contactor, each power contactor is connected with an engine control switch, the engine control switch controls the power contactors to be in linkage at the same time, and the output end of each power contactor is connected to an engine controller. The phenomenon that a certain engine cannot be powered on to work due to single-point faults of a circuit breaker, a switch or a relay can be reduced, and the power distribution redundancy and reliability of an engine control system are improved.
本发明属于直升机发动机控制系统技术领域,具体涉及一种直升机多发动机控制器多余度配电电路及控制方法,电路包括多条供电汇流条以及多个配电模块,所述的多条供电汇流条均与每一个配电模块输入端连接,每个配电模块输出端连接功率接触器,每个功率接触器上连接有发动机控制开关,发动机控制开关控制每个功率接触器同时联动,所述的每个功率接触器输出端均连接在发动机控制器,可以减少因为断路器、开关或者继电器的单点故障而造成某台发动机无法上电工作的现象,提高发动机控制系统配电余度和可靠性。
