Abstract

New RDX-based propellants were obtained and investigated. The heat of combustion was determined in a calorimeter and the pressure history was measured in a manometric bomb. Ballistic parameters, such as maximum pressure, propellant force and covolume of gaseous products, as well as the dynamic vivacity, were determined based on the experimental results. The sensitivities to friction and impact were determined for the tested propellants. Calculations of the ballistic characteristics (the heat of combustion, propellant force, covolume and ratio of specific heats of the combustion products, and ballistic energy) were performed. The theoretical parameters were compared with the experimental data and quite good agreement was found between them. The largest differences occurred in the cases of propellant force and covolume. This disagreement is explained. An analysis of the test results and a comparison of the parameters of the RDX-based propellants and the JA2 propellant allowed the possibility of using the tested propellants in ammunition to be assessed.

新型RDX基推进剂的热化学性质、弹道参数和灵敏度

获得并研究了新型RDX基推进剂。燃烧热在量热计中测定，压力历史在测压弹中测量。根据实验结果确定了弹道参数，如最大压力、推进剂力、气体产物体积以及动态寿命。测定了试验推进剂对摩擦和冲击的敏感性。对弹道特性（燃烧热、推进剂力、燃烧产物的体积和比热比以及弹道能量）进行了计算。将理论参数与实验数据进行了比较，发现它们之间有很好的一致性。最大的差异出现在推进剂力和体积的情况下。这一分歧已得到解释。通过对测试结果的分析以及对RDX基推进剂和JA2推进剂参数的比较，可以评估在弹药中使用测试推进剂的可能性。
