Because of the importance of experiment on aero-engine altitude simulated pressure distortion

the experimental project was discussed in detail. The experiment on aero-engine altitude simulated pressure distortion was launched by moving flashboard. The aerodynamic stability characteristic of aero-engine based on turbulent condition of moving flashboard was obtained

and the magnitude relations of key destabilizing factors such as pressure distortion

altitude low Reynolds number

air bleeding and power extraction to engine stability were obtained preliminarily. The effects of pressure distortion

altitude low Reynolds number

air bleeding and power extraction on critical complex total-pressure distortion descriptor are a fall of 11.11% of complex total-pressure distortion descriptor from altitude 1km to 18km and a fall of 14.69% from altitude 1km to 20km. It provides a testified platform and experimental database for aero-engine altitude aerodynamic stability.
