This paper presents the characteristics of underwater gun′s firing techniques and analyzes the difference between the interior trajectory of normal gun and that of underwater gun.The brief models of underwater trajectory are established by regarding bullet and water column in barrel wholly as a forceacceptor,and the fundamental equations suitable for calculation of underwater gun′s ballistic character are also deduced.Numerical calculation of interior ballistic character parameters is carried out on a typical rod type bullet by using singlebase powder as propellant.Both theoretical analysis and experimental results show that the equations established in this paper are quite adaptable.Several problems that should be paid attention to in underwater interior trajectory design are also discussed by a large number of calculations combined with theoretical analysis.
