摘　　要：针对某直升机电传飞行控制系统,提出了一种能够给电传飞控系统提供可靠供电的供电网络,能实现多余度的供电和供电逻辑重构,有效防止了当系统正常运作时,由于部分电源突然故障并且剩余电源无法供给电传飞控系统,使供电系统过载工作,从而出现飞控系统下电的危险。实验室验证和可靠性计算表明,该方案可极大的提高电传飞控系统供电的可靠性,能够保证飞行安全。To the fly-by-wire control system of a helicopter,a fault isolatable and reconfigurable power supply scheme is proposed in this paper. This power supply scheme could prevent the power supply system from overloading and appearing the power failure of the whole system when the partial power was failed suddenly and the remaining part could not supply the whole flight control system in the normal operation process of the power supply system. The results of laboratory and flight test show that the scheme could improve the reliability of power supply for fly-by-wire control system obviously and ensure the flight safety.
