某型发动机压气机进口可调导叶角度不归位的故障分析

Fault Analysis of an Aeroengine Compressor Inlet Guide Vane Angle Nonhoming

某型发动机的压气机进口可调导向叶片,可根据发动机的工作状态来改变叶片的角度α。出厂时根据发动机转速和推力等参数可调整α在0°^-5°之间,适合于五级放气活门关闭以后的各种工作状态,α在-15°时满足发动机起动状态和由慢车到五级放气活门关闭为止的各个状态。就发生可调导叶角度不归位的故障进行分析。

Compressor inlet guide vane for a certain type of engine, According to the working condition of the engine to change the blade installation angle.According to the engine speed and thrust and other parameters can be adjusted between 0 degrees to -5 degrees, suitable for five bleed valve after the closure of a variety of working condition, ct engine starting state and satisfy each state by train to level five in the bleed valve closed -15 degrees.This paper analyzes reasons of the failure of the adjustable guide vane angle nonhoming.
