Abstract


The launching process of artillery fully immersed in the water is more complicated than that of in the atmospheric environment. In this paper, aiming at the launching process of fully immersed artillery, based on the classical interior ballistic model, the optimum design of internal ballistic parameters was conducted by using multiisland genetic algorithm. Factors such as the work of the projectile on the water column in the barrel, the water resistance of the muzzle and the influence of water depth are all considered. The loading parameters and propellant parameters, such as the chamber volume, projectile travel length, propellant web size, insensitive depth, surface burning rate coefficient correction, mass of charge, etc., are obtained which are satisfying the requirements of maximum bore pressure and muzzle velocity. Engineering analysis of the optimization results are carried out. This paper has certain reference significance for the interior ballistic design of underwater artillery.
