摘要
针对变循环发动机可调节变量多的特点,改进传统的优化方法,并基于遗传算法构建优化程序,综合变循环发动机多个变量进行稳态性能优化。以非加力状态最大推力性能优化结果为例进行展示,结果表明该优化方法克服了传统优化方法的缺陷,充分优化了变循环发动机稳态性能。
By considering the characteristics of many variables that are included in variable cycle engine, the traditional optimization is improved. The optimization program is developed which is based on genetic algorithm. The multi-variables are considered in the steady-state performance optimization of variable cycle engine. The result of the non-afierburning maximum thrust performance optimization is considered as an in- stance. The result shows that the new method can overcome the defects of traditional optimization. The vari- able cycle engine steady-state performance is fully optimized.
