The Random-Choice-Method (RCM) was applied to a numerical simulation of a two-stage light-gas gun. The flow was assumed one dimensional and special procedure was employed at the section with area change. The pressure history at several points and the teminal velocity of the projectile are compared with experimental results at NAL TwoStage Light-Gas Gun. The results agreed very well with the experiments except that the numerical terminal velocities of the projective were 0 to 15% greater than experiments. The present method would become a useful tool in design and operation of such facilities.
