摘要
文中通过对底排—火箭复合增程弹外弹道特征的分析,利用底排总阻减阻率公式推导出了底阻减小率与弹形系数之间的关系。通过简化底排质量流量计算公式并用平均推力代替实际火箭推力建立了复合增程弹的外弹道模型。用所建模型对外弹道参数进行了计算,计算结果与试验结果吻合的一致性较好。所建外弹道模型对该类弹丸的初步设计和弹道参数匹配研究具有重要的指导意义。
On the basis of analysis of exterior ballistic character of compound assistant projectile,deduced a relationship of the ratio of reduction base drag and the coeffic ient of shell shape.A model is built on the relationship as well as simplified base-bleed flowing mass and rocket thrust equation.The calculation results by the model accord with the experiment results very well.The exterior ballistic model have an important guidance on shell design and parameter matching research of this type projectile.
