摘要: 针对某航空发动机离心压气机实施改型气动设计与数值模拟,以达到其“效率提高不低于2%”的性能指标。设计、计算结果表明:改型离心叶轮达到或超过了性能指标要求,可为类似的叶轮机改型气动设计提供借鉴。

Abstract: Aerodynamic redesign of an aero-engine centrifugal compressor impeller was presented.The goal is to increase efficiency by more than two percents.NUMECA Fine/Turbo was used as a numerical tunnel to ensure the design.Results show that the redesigned impeller successfully reached the goal.The experiences accumulated in this procedure are useful for similar impeller aerodynamic designs.
