中文摘要	对某多级轴流压气机前三排叶片径向积叠方案进行了气动优化。该方案以商用软件iSIGHT作为平台,利用试验设计方法对整个搜索空间进行初步探索,采用逐次序列二次规划算法进行局部寻优,利用商业软件NUMECA进行粘性流场数值评估。对压气机全工况性能的计算表明,在流量和压比不减少的情况下,优化后的叶型设计工况和非设计工况性能均得到了改善。; An aerodynamic design optimization of the radial-stacked version of the first three rows of blades was conducted for a multi-stage axial compressor.With commercial software iSIGHT serving as a platform an experimental design method was used for the above version to conduct a preliminary exploration of the whole space being searched,adopting a secondary programming algorithm of consecutive series for localized optimization search.Furthermore,commercial software NUMECA was utilized to make a numerical evaluation of the viscous flow field.Calculations of the compressor performance under all operating conditions indicate that without a decrease in flow rate and pressure ratio the blade profile after the optimization will undergo a performance improvement under both design and off-design operating conditions.
