摘要/Abstract

摘要： 为合理应用高效能膛口制退器于大口径转管机枪系统,基于超音速气体动力学方程,计算了膛口制退器的制退效能;根据刚柔耦合动力学建模理论,对安装不同制退效能膛口制退器后转管机枪在三脚架上的射击运动进行了动力学仿真和外弹道计算。计算结果表明:加大膛口制退器边孔道角度,能有效提高膛口制退效能,减小转管机枪在三脚架上射击时的后坐位移与后坐速度,抑制枪架和枪管弹性变形,大幅度提升机枪系统的射击稳定性和射击密集度。但随着膛口制退器边孔道角度增加至120毅以上,制退效果和对机枪射击密集度提升效果减弱。研究结果为今后转管机枪系统改进、应用膛口制退器提供了参考。

Abstract: In order to apply high-efficient muzzle brake to a large caliber gatling gun system,the muzzlebrake efficiency is calculated based on the gas dynamic equation of supersonic airflow. A rigid-flexiblemulti-body model is established on the basis of rigid-flexible coupling dynamics modeling theory, and the dynamics simulation and exterior ballistic calculation are performed for the shooting of gatling guns withdifferent muzzle brakes on a light tripod. The results show that increasing channel angles can significantly improve the muzzle brake efficiency and reduce the recoil displacement and velocity,restrain the elasticdeformations of tripod and barrel, as well as improve the firing stability and density of gatling gun system.The effect of brake is weakened if the channel angles exceed 120毅.
