摘要
为分析采用电子-液压机械式调节的某型航空发动机加力控制系统的故障部位,以加力状态控制的调节规律和工作原理为基础,建立了以"不能正确进入加力状态"为顶事件的故障树。按照该故障树进行发动机试车典型故障分析,使该故障有效排除。
To find and analyze the fault positon of afterburning control system for a aircraft engine electronic hydro-mechanical control system, a fault tree taking ＂not geting into afterburning condition normally ＂ as top event was built based on the control law andworking theory of afterburning. The typical fault analysis were conducted during the test according to the fault tree. The results show the fault position can find by the fault tree analysis.
