双药室低后坐能弹药技术研究
|
摘要
为了大幅降低火炮发射时的后坐力并保持弹丸初速基本不变,设计了一种双药室低后坐能弹药和验证火炮机构。根据火炮内弹道理论和火箭发动机内弹道理论,建立了一种基于双药室低后坐能弹药的内弹道模型;通过正交试验法分析了弹药后药室喷管喉径、装药质量及燃速对弹药前推力的影响,确定了与弹药前药室底推力规律和总冲量大小相当的最优设计方案,得到了火炮后坐运动部分发射过程中的受力规律。仿真计算表明:发射某中口径火炮弹丸的后坐冲量可减少82. 1%,初步验证了火炮发射双药室低后坐能弹药技术可行,对未来大幅减小火炮的后坐力和提高火炮机动性具有重要意义。
A low recoil energy ammunition with double drug chamber and its verification cannon were designed to significantly reduce the recoil force during the launch of the caliber weapon and keep the initial velocity of the projectile basically unchanged. An internal ballistic model based on low recoil energy ammunition with double-compartment was established according to the theory of artillery ballistics and the theory of rocket engine interior ballistics. An analysis was conducted of the influence of throat diameter,charge volume,and burning rate on the ammunition forward thrust through orthogonal experimental. The optimal design scheme,equivalent to the bottom thrust law of the ammunition and the total impulse,was determined,with the force law during the launch of the moving part of the artillery acquired. The simulated calculation results show that the recoil impulse of launching a medium caliber artillery projectile can be reduced by 82. 1%,with the feasibility of the low recoil energy ammunition technology of artillery launching initially verified. It is of great significance to greatly reduce the recoil force of guns and improve the maneuverability of artillery in the future.
