| 摘 要： | 为保证涡轮/冲压串联组合发动机能够实现平稳的模式转换,对能够实现平稳模式转换的多变量多目标规划算法展开了研究。首先论述了所研究的变循环涡轮/冲压组合发动机的结构特点、模式转换工作点的选取原则、涡扇设计参数和冲压模式设计参数的选取原则,并给出了涡扇和冲压模式的设计点性能。针对模式转换过程的各步骤及其控制目标,发展了部件级变循环组合发动机性能模型。在此模型的基础上,把Newton-Raphson算法运用于模式转换过程的多变量多目标优化研究中。研究结果表明,该算法具有很高的收敛性,满足规划目标的最大残差仅为0.06%。最后,利用上述算法设计了模式转换过程的过渡态控制规律,并完成了平稳模式转换过程的过渡态模拟。
