摘　　要：为对3种不同冷却结构形式的三头部燃烧室冷却效果做出评定,采用K型铠装热电偶和示温漆技术同时对燃烧室3种火焰筒的表面温度进行试验测试研究.试验结果表明:有限的热电偶只能测试局部的火焰筒温度,难以全面反映燃烧室火焰筒冷却效果;示温漆测试技术能有效的区分出燃烧室火焰筒壁面温度及显示温度场分布,示温漆等温线判读精度可达±10℃,为燃烧室3种火焰筒冷却结构效果的评定提供了数据支撑.In order to study the best cooling style for a triple combustor of three differ- ent cooling styles, temperature-sensitive paints and thermocouple were used to study of wall temperature profiles of the flame tube. The result show that, it is difficult to distinguish cooling effect when using a few thermocouples to measure the wall temperature; the best cooling style of flame tube could be analyzed by temperature-sensitive paints, including wall temperature and temperature distribution; the temperature recognition accuracy based on i- sotherm temperature identification is± 10 ℃, the experiment result is an important reference to compare and assess the cooling effect of flame tube.
