摘要:
为了在最大膛压不变的条件下提高弹丸初速,设计了一种再生式液体药辅助药室结构,建立了考虑液滴燃烧过程的内弹道模型,以57 mm高射炮为对象,进行了数值预测.结果表明,辅助药室位置、喷射面积、喷孔长度、喷射活塞差动比和质量等参数对内弹道性能有显著影响.通过这些参数的优化设计,可实现“压力平台”效应,大幅提高弹丸初速.
Abstract:
In order to improve muzzle velocity under a fixed maximum chamber pressure, a kind of structure of regenerative liquid propellant auxiliary chamber was designed. Taking account of the combustion process of droplets, an interior ballistic model was established. Numerical prediction was carried out based on 57 mm antiaircraft gun. The results indicate that the parameters, such as the location of auxiliary chamber, the total injection area, the length of injection orifices, the differential ratio and mass of injection piston, have remarkable effects on the interior ballistic performance. The “pressure plateau” can be achieved, and the muzzle velocity can increase significantly by optimizing these parameters.
