摘要
以某涡扇发动机飞行试验为依托,研究航空发动机简化模型的建模方法和思路,并通过飞行试验对模型进行验证。运用所建立的发动机加速实时模型对发动机加速性能进行优化,并通过飞行试验验证优化方法的有效性。结果显示,基于飞行试验所建立的发动机加速模型精度满足要求,能够有效指导发动机加速性能优化措施的制定。
Based on the flight test of a turbofan engine, the modeling method for the simplified model of aeroengine is studied in the paper, and the model is validated by the flight test. Then, the model is used to optimize the acceleration performance of engine, and the validity of optimization is validated. The results show that the precision of the model can meet the requirement, which can effectively guide the optimization of the acceleration performance of aeroengine.
