摘　　要：针对气冷涡轮效率定义方法进行了研究,首先介绍了几种常用的气冷涡轮效率定义,即气动热力学效率和涡轮级效率,并对这几种气冷涡轮效率定义进行了比较分析,最后以某一双级高压涡轮为例,分析了不同气冷涡轮效率定义方法对计算结果的影响。To investigate the definition methods of the air-cooled turbine efficiency, several definition methods of air-cooled turbine efficiency are introduced, i.e. thermodynamic efficiency and stage efficiency. The modeling methodology differences between different efficiency definition methods are analyzed, and taking a two-stage high pressure turbine as an example, the influence of different efficiency definition methods is analyzed.
