摘　　要：为了更好地研究拉瓦尔喷管减后坐结构对自动武器减后坐效率的影响,该文设计了一种改进型制退器,在制退器两旁引出向后的拉瓦尔喷管,膛内燃气经导气孔进入拉瓦尔喷管后加速喷出。以某7.62 mm机枪为实验枪,以弹丸初速和减后坐效率为研究对象进行实验研究,通过实验得到了在不同方案下的弹丸初速和枪身减后坐效率的曲线。实验结果表明:两种减后坐技术都能在不明显减少弹丸初速的情况下,得到较好的减后坐效率,并且联合使用两种减后坐技术能够得到更加理想的减后坐效率。To better learn the efficiency of recoil reduction by Laval nozzles acted on automatic weapons,an improved brake is designed to reduce recoil.Backward laval nozzle are located at both sides of the brake.In-bore gas flowing into the Laval nozzles through gas ports sprays accelerately.Taking 7.62 mm machine gun as an experimental gun and taking the muzzle velocity of projectile and the efficiency of reducing recoil force as the research objects,the experiments achieve the curves of the muzzle velocity of projectile and the efficiency of reducing recoil force for different projects.Experimental results indicate that two kinds of recoil reduction technologies can improve the efficiency of recoil reduction without reducing the muzzle velocity of projectiles significantly.The combination of the two technologies can obtain the better efficiency of recoil reduction.
