Abstract
Abstract The protection performance is needed higher and higher in the development of a modern war. However, with the increase of the projectile kinetic energy, the recoil will increase as well, which brings disadvantages in the gun weapon systems. In this paper, a new recoil gun with a blasting device based on the rarefaction wave is developed to meet the demand of reducing the recoil without loss of the kinetic energy. The physic process of the rarefaction wave gun is studied by a two-phase flow model of interior ballistics. Then the effects of nozzle structure parameters of the low recoil gun are investigated. Based on the study of parameters, an optimized nozzle structure is given. The muzzle velocity reduces only 0.61% and the recoil impulse reduces by 38.5%. The study provides a theoretical direction for the development of low recoil gun weapon.
