摘要
目的 研究底排火箭复合增程弹最佳外弹道参数匹配方案. 方法 通过对复合增程弹外弹道速度层权和阻力系数层权的计算, 分析了外弹道特征, 并利用外弹道仿真软件, 对复合增程弹外弹道进行了计算. 结果 根据外弹道计算的结果, 给出了底排、火箭装药量及其它参数与弹丸射程的关系, 并给出了在总装药量一定的条件下, 底排、火箭装药之间最佳匹配关系. 结论 通过对弹道参数匹配方案的研究,
Aim To optimized exterior ballistic paparmeter matching scheme of hybrid range enhanced shell by base bleed and rocket. Methods The velocity weight and resistance weight in the range enhancement are analyzed and simulated. Results According to the calculated results, relations between base bleed charge and rocket charge as well as other parameters with the range are given. An optimized parameter match scheme is given on the condition that the total charge auantity is maintained constant. Conclusion An impotant guidance on the collectivity structure parameter designing is available with this matching scheme.
