Abstract:
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.
