摘要
基于双变量曲面拟合,本文发展了轴流压气机和涡轮特性计算的新方法。该方法避免了发动机性能模拟中冗长耗时的部件插值计算。用新方法计算了某型涡扇发动机的压气机和涡轮特性。计算结果与实验结果吻合很好,表明了新方法的有效性。
Based on two variable surface fit, an analytic method for computing the axial-flow compressor and turbine characteristics was developed. The method was used to calculate the exemplary compressor and turbine characteristics of a turbofan engine. Compared to experimental data, the numerical results show good agreements. It is remarkable that this method is practicable.
