供压状态影响操纵台通道灯亮灭的机理分析

Mechanism Analysis of Impact of the Supply Pressure State on the Channel Lamp of Control Console

电传操纵系统通道故障灯亮灭是由监控电路根据各级表决故障信息判断产生,监控电路较复杂。飞机通电和供给液压时,通道灯时亮时灭,状态多种,是电传操纵系统故障监控电路作用的结果。阐述液压系统供压状态影响座舱ПУ-220/353操纵台通道灯亮灭的工作机理。

Monitoring circuit is a very complex system. The phenomenon that the trouble lights of fly - by - wire control system are out and on is the result of monitoring circuit according to the vote on various fault information. When the plane is electrified and supplied hydraulic, the state of channel lamp is the result of fault monitoring circuit of fly - by - wire control system. The operating principle that the states of supply pressure by hydraulic system have effect on channel lamp of cockpit ПУ - 220/353 control console is discussed in this paper
