Application of Holographic Interferometry to the Exterior Ballistic Flow Field in the Muzzle Environment of a Twenty Millimeter Cannon.
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.
