发射药的火焰燃烧温度计算与测定分析

摘要

The burning temperature of single-based (H100 and H130 ) ,SF (SF-3) ,modified double-based propellants (171-25 and GT) were calculated and measured at constant pressure.The difference between adiabatic flame temperature approximation calculation result and measured result was compared.The calculation results are consistent with experimental results,the maximum flame temperatures of H130 and SF-3 propellant are 2215 K,2230 K.As the candidate of hot source,the double-based propellant is better than the single-based propellant.The colorimetric temperature measurement can not reflect the accurate temperature of modified double-based propellants.%采用绝热火焰的定压近似计算法,对单基药H100和H130、双基药SF-3、改性双基药171-25和GT的火焰燃烧温度进行计算,并采用比色红外测试仪测量发射药的实际温度.结果表明,H130、SF-3试验结果与计算值比较吻合,其最高燃烧温度为2188 K和2230 K;用于热源时,双基药的性能优于单基药;利用该比色测温仪无法获得改性双基药火焰燃烧温度的真实值.
