某型延寿助推器内弹道性能预示

Prediction on the Interior Ballistic Performance of an Extended Missile Roll Booster

摘要:

在建立某型延寿助推器翼柱型装药的仿真模型和数学模型的基础上,对该型助推器装药进行了数值模拟,完成了内弹道性能预示,得出了该型延寿助推器燃烧室压强和推力随时间变化的规律,并根据内弹道性能预示结果分析该型延寿助推器继续使用的可能性。

Abstract:

On the basis of developing the simulation model and math model of a prolonging the lifespan’s booster’s finocyl grain, the make numerical simulation was done and the interior ballistic performance prediction was accomplished. The pressure and the trust law with the change of time were obtained. And according to the prediction result, the possible of the booster’s normal usage was analyzed.
