摘要:

针对现有航空涡轮发动机部件特性自适应模型中存在的不足,提出了合理的解决方法:根据测量参数合理选择部件特性修正因子;使用部件特性删除法求解部件特性修正因子;部件特性修正因子的数值拟合方法。采取这些改进措施后,使得现有航空涡轮发动机部件特性自适应模型得到改善。计算结果与两种型号的涡喷发动机的试验数据对比表明本文的改进方法合理。

Abstract:

For overcoming some insufficiencies of adaptive simulation model of gas turbine performance at present,some reasonable solutions were proposed as follows: a reasonable choice of the modified coefficients according to measure parameters;a method of solving the modified coefficients without component maps;a polynomial fit of modified coefficients.The current adaptive simulation model of gas turbine performance was improved by using these solutions.Compared with experimental data,the computing results of two type turbojet engines indicated the solutions were feasible.
