        Abstract
        The technique of holographic interferometry was applied to the study of the gas core characteristics in the muzzle environment of a 20 mm cannon. Experimental measurements were made of the muzzle velocity and of gas core pressures at the cannon breech to verify prediction of these parameters in a numerical technique using standard hydrodynamic equations. Holographic interferograms were made of the projectile and its associated flow field during launch.

          Comparison of two railgun power supply architectures to quantify the energy dissipated after the projectile leaves the railgun 

          Stewart, Mitchell C. (Monterey, California: Naval Postgraduate School, 2016-06);
          Railgun muzzle flash, or post-fire arcing, is a major concern to the Navy because of the potential associated thermal stresses. In this thesis, we compared two railgun power supplies in Matlab Simulink to quantify their ...

          Velocity and pressure effects on projectiles due to variation of ignition parameters 

          Culver, Richard Otis; Burns, Raymond Michael. (Naval Postgraduate School, 1972);
          The effect of varying the point of ignition of the powder charge within a cartridge case was investigated with respect to both pressure and velocity. By installing a small tube in the base of the cartridge case it was ...
