【摘要】：為對3種不同冷卻結(jié)構(gòu)形式的三頭部燃燒室冷卻效果做出評定,采用K型鎧裝熱電偶和示溫漆技術(shù)同時對燃燒室3種火焰筒的表面溫度進(jìn)行試驗(yàn)測試研究.試驗(yàn)結(jié)果表明:有限的熱電偶只能測試局部的火焰筒溫度,難以全面反映燃燒室火焰筒冷卻效果;示溫漆測試技術(shù)能有效的區(qū)分出燃燒室火焰筒壁面溫度及顯示溫度場分布,示溫漆等溫線判讀精度可達(dá)±10℃,為燃燒室3種火焰筒冷卻結(jié)構(gòu)效果的評定提供了數(shù)據(jù)支撐.
[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 鹵10 鈩，
