AB Variable Bleed Valve (VBV) as the core component of aero-engine compressor air flow control, plays a vital role in eliminating the risk of booster stall during transient conditions, and is an important foundation to ensure the stable operation of engine and the flight safety of aircraft. In this paper, the VBV of a certain engine is studied to build its function model and carry out the system simulation analysis based on AMESIM. Secondly, the control system simulation model is established by using MATLAB and aircraft Quick Access Recorder (QAR) data. In combination with the function model and the control model, the working characteristic curve of VBV is analyzed and compared with the actual working characteristic curve of the engine. The results show that the variation trend of simulation characteristic curve is consistent with the real characteristic curve, which fully verifies the accuracy and reliability of VBV functional model.
