热电偶法测量硅系延期药燃烧温度的研究

摘要

Pt-Rh thermocouple is used to measure combustion temperature of silicon delay-composition. The combustion state of singe delay composition is simulated, and the delay composition is loaded in a steel thick tube by several times with the density is 2.40g/cm3. The highest measured temperature is 1583℃ at the mainly heat-accumulation area. Most of the combustion heat loses in the transmission to the shells and so on, and the much lower temperature is measured after 35ms.%采用R型铂铑合金热电偶的方法测量硅系延期药的燃烧温度,模拟单芯延期体的燃烧状况,将延期药以2.40 g/cm3的压药密度,分次均匀压入厚壁钢管中.在热量积累最多的区域内,实验测得硅系延期药的最高燃烧温度为1583℃.燃烧热有很大部分传递给外壳等物质而散失掉,35ms后测出的温度较低.
