发动机加速过程的优化建模方法研究

航空发动机数学模型通常使用部件法建模，这种方法算法较为复杂，收敛性差，且实时性差，因此建立适合半物理实验使用的数学模型比较困难。本文提出这种建模方法是基于发动机的稳态试车数据，主要研究动态过程中，供油量与发动机主要参数的对应关系。该程序算法易懂，实时性好，计算效率高。计算机仿真的结果与试车数据基本一致。通过分析某型发动机半物理试验结果，表明该数学模型可以满足实验需求。

Research on optimal Modelling the acceleration process of Aeroengine

Aeroengine model usually developed on component-level. The algorithm of this method is complex. It is both poor of astringency and instantaneity.So it is difficult to develop a aeroengine model for the semi-physical simulation. Based on engine ground steady state test data,a new modeling method is developed in this article.It discusses the relationships between the fuel and the parameters of the engine in the dynamic process mainly. It is easy to understand the algorithm of the program. And It is do well in instantaneity and has a high efficiency calculations.The results of simulation by the computer agrees with the test datas.It is indcated that this methed of aeroengine model satisfied well according to the semi-physical simulation.
