摘要
实验研究了工业级RDX粒度对复合改性双基推进剂(CMDB)力学、燃烧及感度性能的影响。结果表明:黑索今平均粒径从92.02μm减小到17.35μm时,相应地固体推进剂高温最大抗张强度提高54%,低温延伸率提高85%;推进剂的燃速在不同压力下均有增加,最大增加11.5%;撞击感度特性落高增加5.1cm,摩擦感度爆炸百分率下降75%。
The effects of RDX particle size on properties of CMDB propellant including mechanical property,combustion property, sensitivity property and energy property were studied. The results show that when RDX particle size changes from 92.02 μm to 17.35 μm,correspondlng maximum tensile strength of CMDB propellant is enhanced by 54% at high temperature （50 ℃ ） and the elastic elongation is enhanced by 85% at low temperature （ -40 ℃ ） respectively. Meanwhile ,the burning rate of propellant at different pressure increases by 11.5% at its maximum. The characteristic height of impact sensitivity increases 5.1 cm,and the explosion percentage of friction sensitivity decreases by 75%.
