One-dimensional characteristic optimization design for ten-stage high pressure compressor in commercial engine

  • 摘要: 采用HARIKA算法对某商用发动机10级高压压气机进行了一维特性预测.引入遗传算法优化设计手段,以压气机一维设计参数为优化变量,设计转速下特性线的峰值效率、裕度为优化目标函数.与初始特性线相比,压气机在优化后设计转速时特性线的峰值效率提高了12.3%,裕度由11.7%提高到25.13%.对变几何压气机特性进行了优化分析,给出不同换算转速下进口导叶及前3级静子叶片安装角的最佳调节规律.优化后的压气机在非设计转速下的效率特性得到了大幅提升,压比特性得到了提高,流通能力也得到了加强.将压气机一维优化的特性线与采用一维优化设计参数得到的全三维计算结果在1.0,0.9倍换算转速下进行了对比,两者预测出的喘振边界在最大偏差处不超过6.25%.
