Numerical simulation on interior ballistic of central combustion gas dispersing system with spoiler

摘要: 为了研究扰流板对子母弹抛撒过程中子弹翻转角速度的影响规律，采用二维两相流模型对子母弹中心燃气式抛撒内弹道过程进行了数值模拟研究。通过计算结果和测试结果的对比，验证了数值模型的可行性和准确性。对流场结构和推弹装置受力状态的对比分析表明，当燃气发生器小孔集中于扰流板上侧时，提高扰流板位置可以有效增大推弹装置受到的翻转合力矩。可为同类型抛撒系统的设计和改进提供理论参考。Abstract: In order to study the influence of the spoiler on the overturning angular velocity of the ammunition in the dispensing process, the central-gas dispersing interior ballistic process was modeled and simulated by a two-dimensional, two-phase flow model. The comparison between the numerical simulation results and the test results proved that the above model was feasible. The comparative analysis of the flow field structure and the ejector stress states shows that the turning torque of the ejector can be enhanced by elevating the spoiler when the holes of the gas generator are on the top of the spoiler. And the final result can provide a theoretical basis to improve the submunition dispersing system.
