A technique for adjusting the attack angle of aero-engine compressor inlet guide vane through LabVIEW is introduced.Based on the virtual instrument programming technology,this technique focusses on re-development of flight parameters to realize the intuitive display of the deflection characteristics of aero-engine compressor inlet guide vane when the aero-engine is running.The simulation of the adjustment process of the guide vanes attack angle,the debugging conditions and the evaluation of the adjustment results are realized by the visualization of virtual instrument,so virtual debugging and effect evaluation of deflection angle of guide vane are realized,which can be used to guide the actual debugging of the aero-engine.The test results show that this method can be effectively applied to monitor and adjust the deflection performance parameters of aeroengine guide vane,and prevent the occurrence of faults.Compared with the traditional manual experience debugging method,it can reduce the fuel consumption during the debugging process,and extend the aero-engine life which produces higher economic value.
