Research into the Internal Ballistic Performance of A Weapon with Recoiled Reduced by Double-chamber Partition Controlling Backfire
In order to solve the problem of excessive recoil during the launch of a new grenade launcher at high muzzle velocity,this paper uses the technology of double-chamber partition con-trolling backfire for recoil reduction and the two-phase flow internal ballistic theory to carry out theoretical modeling and numerical simulation of the weapon launch process.Compared with the experimental results,the correctness of the model and algorithm is verified.Compared with the in-ternal ballistic performance of ordinary weapons,it is confirmed that the double-chamber partition controlled backfire recoiling technology can reduce the recoil of weapons.Prototypes are developed and tested.The results show that the recoil impulse of a seapon with recoil reduced by double-chamber partition controlling backfire decreases from 114.798 N·s to 28.47 N·s,and the recoil reduction efficiency is 75.199%.
