摘　　要： 单级离心压气机在微型航空发动机中有着十分广泛的应用,为了探索高速的离心压气机设计技术,利用参数造型方法完成了一台压比为3.2的离心压气机设计,总结了离心压气机的关键设计方法。主要的设计过程为:经过一维方案设计完成初始参数选择,再以二维流通计算为基础,通过调整叶片环量分布来完成叶轮三维造型,最后使用数值模拟软件来分析气动设计的性能结果。结果表明:离心压气机在设计工作点的内部流动参数分布合理,各项性能参数都能够满足设计要求。 Single-stage centrifugal compressors are widely used in micro turbojet engine. In order to explore the design technology of high speed centrifugal compressor, a high speed centrifugal compressor with pressure ratio of 3.2 is designed using parameterization modeling method and summarized the key design method. The main design process was included of one-dimensional （1D） conceptual design to complete initial paratmetric selection, and based on two-dimensional （2D） through flow calculation, the aerodynamic design performance was obtained by finally using numercial simulation software analysis, through adjusting the distribution of velocity circula- tion to complete the three-dimensional （3D） modeling of blade rows. The results show that the performance and parameters of designed centrifugal compressor are reasonable in distribution for internal fluid working points, and can meet all the requirements in design.
