摘　　要：为快速获取轴流压气机气动设计方案,缩短设计周期,建立了一套基于多流线法的准二维快速气动设计方法,开发完成相应的设计程序。该方法使用由简化径向平衡方程推导的多流线法,在一维平均中径法设计的基础上引入多条流线并嵌入物性计算软件提高计算精度,求解得到不同径向位置上的流场气动参数,无需进行流线反复迭代。通过与叶片造型衔接,生成压气机几何模型并进行三维数值模拟,获取初始设计方案的流场细节。为验证程序和方法的准确性,参照某跨音风扇算例的设计参数,设计并验证了一个单转子压气机的性能。结果表明:设计的单转子子午流道几何结果和性能基本满足轴流压气机初始设计方案要求,多流线方法可以在轴流压气机初始设计阶段更快速、稳定地提供气动设计方案。In order to rapidly obtain the aerodynamic design scheme of axial compressors and shorten the design cycle,a quasi-two-dimensional rapid aerodynamic design method based on the multi-streamline theory was established,and the corresponding design programs were developed.To do this,the multistreamline approach was derived based on the simplified radial equilibrium equation.After multiple streamlines were introduced based on one-dimensional mean-line design and they were embedded in physical property calculation software to improve calculation accuracy,it can determine aerodynamic parameters of the flow field at different radial positions,without the need for repeated streamline iterations.By connecting with the blade profiling,the geometric model of the compressor was obtained and then subjected to three-dimensional numerical simulation to obtain the flow field details of the initial design scheme.To verify the accuracy of the program and the method,the performance of a single rotor compressor was designed and validated based on the design parameters of a transonic fan example.The results show that the geometry and performance characteristic of the designed single rotor meridional flow path basically meet the requirements of the initial design scheme of the axial compressor.The multi-streamline method offers an aerodynamic design scheme more rapidly and stably in the initial design stage of the axial compressor.
