摘要
通过定容燃烧实验比较了含局部阻燃火药的模块装药中各装药组分及其混合装药的燃烧性能。结果表明,定容燃烧实验中局部阻燃火药的混合装药p-t曲线拐点处的相对已燃烧部分Ψe值随装填密度的变化而变化。通过不同装填密度的混合装药中止实验,分析了Ψe值变化的原因。由势平衡理论结合实验数据分析表明,Ψe值变化与实际模块装药火炮内弹道p-t曲线上势平衡点的相对已燃烧部分ΨE值变化相对应。在模块装药中,局部阻燃火药能起到调节膛压的作用。
The combustion performance of components of modular charge and their mixed charge was comparedthrough closed bomb experiments.The result showed that the characteristic that the relative combustion part W.atthe inflection point of p-t curve of PFR propellants charge varied with the loading density was found in closed bombexperiments.Reasons of the change of W。were analyzed by the intercepted combustion experiments.From the poten-tial equilibrium theory and the analysis of experimental data,it is indicated that the change of W,corresponding to thechange of Wz at the potential equilibrium point of p-t curve in interior ballistic experiments of modular charge,Thechamber pressure can be controlled by the PFR propellants in modular charge.
