查询词典 propellants

By designing the mould to change the propellants model frame, selecting differentmaterials as propellant seal layer agents, studying the preparation technics, we havepreferably solved the PSS seal layer pressurize and combustion disciplinarian problem, andobtained the remarkable increasing burning surface effect.The practical increment ofΓvalue reachs 3.2 upwards conducting closed bomb firings, comparing with 19 holepropellants—the best progressivity burning in the present, whose practical increment ofΓvalue is 1.2, the PSS amplitude ofΓvalue exceeds 2.5 times.

通过药型结构和模具的设计、端面密封材料的选择和制备工艺的研究，较好地解决了PSS发射药的端面密封和燃烧规律控制问题，获得了显著的增面性燃烧效果，密闭爆发器实验中燃气生成猛度的实际增量达到了3.2以上，与目前增面性最好的19孔发射药实际增量的1.2左右相比，增幅超过了2.5倍。

Mechanical properties and combusition characteristics were affected evidently by the solid grain configuration and its character. Mechanical propertiesof the material system could be improved by adopting RDX and proper granularpropellants granularity rank-match. It is favorable to obtain progressivity burning effect byaffiliating increasing burning surface propellant grains. Affiliating fast burning componentthese burning rate regulator in the bond system can quicken burning rate of propellants andimprove burning progressivity.

固体颗粒形态及其性质对力学性能和燃烧性能具有较大的影响，采用RDX与适当颗粒度的固体发射药的粒度级配有利于改善力学性能，加入增面燃烧的发射药颗粒，有利于获得渐增性的燃烧效果，在粘合剂体系中加入速燃组份等燃速调节剂，可加快发射药的燃气生成速率，改善燃烧的渐增性。
