摘要: 本文主要针对压气机和涡轮核心部件性能衰退开展研究。考虑三种情况：压气机性能老化，涡轮性能老化，压气机和涡轮部件性能同时老化，将部件性能老化模型插入到发动机稳态计算模型中修正部件特性，得到对应的涡轮部件性能变化。基于流场仿真技术建立匹配的涡轮部件模型，依据性能衰退模型修改涡轮进出口边界条件和转速，得到涡轮气流流场和压力场分布，进一步分析了性能衰退前后的涡轮性能。所得结论对单个部件乃至整机性能衰退以及各部件之间的相互影响具有一定参考价值。
Abstract: This paper focuses on the performance degradation of compressor and turbine core components. Considering three conditions: performance deterioration of compressor, turbine, compressor and turbine, embedding component performance deterioration model into stable engine computation model and modifying component characteristic, change of turbine component was analyzed. The matching turbine component model was established based on floating field simulating technology, the turbine floating field and the pressure field were calculated by modifying inlet and outlet boundary condition and rotor speed based on deterioration model, and the total performance was analyzed around performance deterioration. The results offer theoretical reference to single component even engine performance deterioration and effect between components.
