国外航空发动机空气动力学研究概况

An Overview of Aero-Engine Aerodynamics Overseas Research

在航空发动机研制过程中,会遇到一系列空气动力学问题,尤其是压气机、燃烧室、涡轮等重要部件的研究,需掌握复杂的空气动力学流动机理与物理现象。对此,国外进行了大量研究。本文综述了国外主要航空大国在航空发动机空气动力学研究方面的基本情况,主要包括研究机构设置、主要研究工作及重要研究设备。最后,结合国内的研究现状,为我国开展航空发动机空气动力学研究提出几点建议。

The aero-engine development will encounter a series of aerodynamic challenges, especially for vital components such as compressor, combustor and turbine. A great deal of such study had been per-formed overseas in the past decades. An overview of aero-engine aerodynamics research conducted in ma-jor aeronautical countries was presented, including research units setup, main research work and test facili-ties utilized. In the end, several proposals for our own aero-engine aerodynamics research were given.
