【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.
[Abstract]:In order to evaluate the cooling effect of three types of three-head combustor with different cooling structures, the surface temperature of three kinds of flame tubes in the combustion chamber was tested and studied simultaneously by using K-type armored thermocouple and temperature-indicating paint technology. The test results show that the limited thermocouple can only measure the local flame tube temperature, which is difficult to fully reflect the combustion chamber flame tube cooling effect, and the temperature indicating paint testing technology can effectively distinguish the combustion chamber flame cylinder wall temperature and the temperature field distribution. The accuracy of the isotherm interpretation of the temperature indicating paint can reach 卤10 鈩，
