| 摘 要： | 针对高空风车条件下涡扇发动机起动性能估算问题, 提出了运用约简遗传规划算法进行模型结构自动选择的思路, 对基于约简遗传规划的风车起动模型进行了研究.以某型涡扇发动机为例, 运用该算法对给定条件下该型发动机的风车起动过程进行了建模仿真, 得到了起动过程的估算结果.将估算结果与试验数据对比, 验证了方法的正确性、可行性.

| Abstract: | In order to solve the problem of turbofan starting characteristics estimation under windmilling condition,an approach to automatic selection of model structure via Parsimonious Genetic Programming(PGP) was presented.The engine windmilling starting model based on PGP was also studied.The starting characteristics of a certain turbofan under windmilling condition were modeled and simulated by this method.It is proved to be correct and feasible if the estimation results are compared with the experimental data |
