摘要
本文利用辐射高温计ROTAMAPII测量了某型燃机二级涡轮转子叶片的发射率。通过对该燃机的试车获取了多个试验状态的数据,对试验状态9 100 r/min、2 260 kW下的试验数据进行分析表明,该燃机涡轮叶片温度场与理论要求是吻合的。
This paper gained the emissivity of the second rotor blade in a gas turbine engine using an infrared thermometer named ROTAMAPII. Data at several operation conditions were acquired through this investigation of a gas turbine engine. The analysis of measurements taken at 9 700 r/min （2 260 kW） revealed the temperature fields of the blades in gas turbine engine in accordance with theoretical data.
