摘要:

阐述了在某型涡喷发动机上测量涡轮前、后温度分布的方法，并对测量结果进行了分析，得出"涡轮后温度分布不能代替燃烧室出口（涡轮前）温度分布"的结论。

Abstract:

The temperature profile quality at engine combustor exit (before turbine) is aimportant technical index, which concern operational reliability and life of engine’s thermalcomponent, thus measuring temperature profile at the combustor exit (before turbine) in a engine isvery important. The method of measuring temperature profile before and after turbine in a typeturbojet is presented and the measured results is analysed. It can be concluded that the aftertemperature profile turbine differs from the one before turbine.
