类比国家及行业标准中有关固体燃料燃烧热值的测定过程及结果表征,研究基于恒温式氧弹量热计对偏二甲肼这一易挥发性双组元液体推进剂的燃烧热值测定方法,分析了易挥发性样品的密封处理、充氧压力、点火失败原因等;对比国外标准发现,测定结果重复性的提高是待解决的关键,对一系列自然贮存偏二甲肼氧化样品及加入偏腙处理后样品进行了燃烧热值的测定,并将测定结果与组分分析结果进行对照。结果显示,燃烧热值降低程度与偏二甲肼氧化后产物的体积比相关。
Analogy of the national and industry standards on the determination of solid fuel combustion calorific value and characterization of the study based on the constant temperature bomb calorimetry UDMH this volatile dual component liquid propellant combustion calorific value method , Analysis of the volatile sample sealing treatment, oxygenation pressure, ignition failure reasons; compared to foreign standards found that the determination of the repeatability of the improvement is the key to be resolved, a series of natural storage of UDMH oxidation samples and added The sample after the partial hydrazone treatment was used to determine the calorific value of the combustion and the results were compared with those of the component analysis. The results show that the degree of reduction of the calorific value of the combustion is related to the volume ratio of the product after the oxidation of the unsymmetrical dimethylsulfoxide.
