Study on Two-Dimensional Interior Ballistics Model of Solid Propellant Electrothermal Chemical Gun

建立了描述固体工质电热化学炮内弹道过程的轴对称二维模型,计算结果与实验符合良好,证实了模型的可行性。二维模型可以给出膛内参数的详细分布,为细致研究等离子体点火及燃烧增强过程提供了有力的工具,并可以应用于实验方案预测及分析。

An axisymetric two-dimensional model is presented to describe the internal ballistics of solid propellant electrother- mal chemical gun.The calculated results accord well with experimental results.This suggests the feasibility of the model.Re- sults of two-dimensional model show detailed distribution of ballistics parameters.The model provides an effective way to further investigate the process of plasma ignition and combustion augmentation.It can also be applied to prediction and analysis of ex- perimental projects.
