| 摘 要： | 为了更好地降低自动武器后坐力对射击精度的影响,该文提出了一种利用膛内燃气通过拉瓦尔喷管气流反推减后坐力的新型自动武器结构,建立了双一维两相流数学模型,并以5.8 mm口径实验枪为研究对象进行数值模拟计算仿真.结果表明:该结构能在不明显减小弹丸初速的同时,起到明显的减后坐力的作用,减后坐效率达到37.8%.

| Abstract: | In order to reduce the impact of the recoil force of automatic weapons on shooting accuracy,a new structure with Laval nozzle by using the high-pressure gas in chamber to achieve low recoil force for auto-weapons is proposed.A duo one-dimensional two-phase flow model is developed.And the 5.8 mm test gun is taken for numerical simulation.The result demonstrates that the new structure is capable of reducing recoil force without dropping the velocity of pull when it is out of chamber,and the efficiency for red... |
