为了提高高负荷压气机气动性能,探索高负荷压气机设计方法,首先对高负荷压气机轴向载荷和参数分布进行研究与筛选优化,然后利用二维正/反问题设计与分析方法优化压气机载荷展向分布,最后利用三维流场分析方法进行精细分析,从而使高负荷压气机级间参数达到良好的匹配。将该方法应用于一台高负荷压气机设计中,并将试验值与计算结果进行了比较分析。结果显示:该技术有效地提高了压气机全工况的性能,使压气机各级工作在合理的参数下,相对于第四代发动机的压气机平均级压比提高了16%,效率提高了1%。
In order to improve the aerodynamic performance of high-load compressor and explore the design method of high-load compressor, firstly, the axial load and parameter distribution of high-load compressor are studied and optimized. Then, the design and analysis of two-dimensional forward / inverse problem are used to optimize the compressor Load distribution, and finally use the three-dimensional flow field analysis method for fine analysis, so that high-load compressor stage parameters to achieve a good match. The method is applied to the design of a high-load compressor and the experimental results are compared with the calculated results. The results show that this technology can effectively improve the performance of the compressor under all working conditions, and make all levels of the compressor operate under reasonable parameters. The average compressor pressure ratio is increased by 16% compared with that of the fourth generation engine, and the efficiency is improved 1%.
