| 针对某型发动机低压压气机导流叶片角度低于标准值即偏关的故障，详细分析了故障现象，阐述了低压压气机导流叶
片调节通道工作原理及控制计划，剖析故障机理。根据所制定的排故流程，提出并分析了可能引发该故障的综合电子调节器、电路、
传感器故障模式，最终确定综合电子调节器故障导致低压压气机导流叶片角度低于标准值。更换综合电子调节器，进行外场试车验
证。结果表明：发动机工作参数正常，推力稳定，低压压气机导流叶片角度符合要求。 |
| 英文摘要: |
| the fault on an aeroengine guide vane angle of the low pressure compressor lower than the standard values，
phenomenon was analyzed in detail,the channel control schduleand working principle were expounded，and the fault mechanism was
analyzed.The possible causes of electronic controller failure，the circuit failure and the sensor failure were listed and analysed.The analysis
shows that the angle of the guide blade of the low pressure compressor was lower than the standard value due to the failure of the electronic
controller failure. The field test verification is conducted by replacing the engine controller，the test results show that the engine work
parameters are normal and the thrust is stabilize，the angle of the guide vane of the low pressure compressor is congruent. |
