摘要
Abstract
In order to study recoilless structures with laval nozzles, a new technical structure was designed,which was two-hole recoilless structure with laval nozzles. The dynamic model of launching process was established by one-dimension two-phase-flow theory. Taking 23 mm test gun as research object,numerical simulation was carried out,and the influence of the distance between the two holes on the muzzle velocity of projectile and the efficiency of reducing recoil force were analyzed. The numerical simulation results were compared with the single-hole front-nozzle structure. Compared with the single-hole front nozzle structure,the best efficiency of reducing recoil force reaches 32. 85% , while the muzzle velocity of projectile don't reduce significantly.关键词
