航空发动机加力接通异常故障分析与研究

Analysis and Research on Abnormal Fault of Aeroengine Afterburner Engagement

某型号航空发动机在空中发生禁止接通加力故障,原因是喷口加力调节器上安装的Lo传感器发生故障,导致加力控制系统禁止发动机接通加力。通过故障机理分析准确给出故障原因判断方法和处置方法,并提出相应的排故流程和保障建议。

A certain type of aeroengine has an in-flight afterburner failure,which is caused by the failure of Lo sensor installed on the nozzle afterburner regulator,leading to the afterburner control system prohibiting the engine from switching on afterburner.Through fault mechanism analysis,accurate fault cause judgment methods and disposal methods are given,and corresponding troubleshooting processes and support suggestions are put forward.
