摘要
在经典无坐力炮内弹道学理论的基础上引入了不平衡冲量的计算方法,建立了计算模型,该计算模型与试验结果吻合较好。利用此平衡内弹道算法分析了弹丸挤进压力、堵片打开压力、火药弧厚、喷管面喉比等设计参数对不平衡冲量的影响。研究结果表明:喷管面喉比对不平衡冲量的影响较大,弹丸挤进压力、堵片打开压力、火药弧厚对不平衡冲量的影响较小。研究结果可为无坐力身管武器的相关设计提供参考。
In order to study the unbalance impulse of the recoilless gun during its launching,the calculation method of unbalance impulse was introduced on the basis of the classical interior ballistic of recoilless gun,and the calculation model of unbalance impulse was established.It was shown that the calculation model is in good agreement with the experimental results.The influence of design parameters such as projectile extrusion pressure,blockage opening pressure,powder arc thickness and nozzle-to-throat ratio on the unbalanced impulse was also analyzed by using the equilibrium interior trajectory algorithm.The results show that the ratio of nozzle face to throat has a great influence on the unbalance impulse,while the extrusion pressure of projectile,the opening pressure of block and the thickness of gunpowder arc have little influence on the unbalance impulse.The research results provide some reference for the design of the unbalance impulse of the recoilless barrel weapon.
