Abstract : A mathematical model describing the interior ballistics of a smooth bore experimental gun has been used to optimise the composition of a composite propellant charge for achieving muzzle velocities of 1500 m/s with projectiles of 23 g (0.051 1b). Comparison of predicted and experimental results indicate, however, that this gun is subjected to excessive leakage. If this problem can be overcome, muzzle velocities of 1900 m/s may be attained using the recommended composite charge and existing gun specification. (Author)
