Application of Holographic Interferometry to the Interior Ballistic Flow Field in the Barrel of a Twenty Millimeter Cannon.

Abstract

The technique of holographic interferometry was applied to the study of gas core characteristics in the barrel of a 20mm cannon. Using standard hydrodynamic equations theoretical predictions were calculated. Holographic interferograms were made of the associated flow field near the projectile during firing. Reconstruction of the wavefront provided the necessary means of comparing experimental results with the theoretical values obtained. (Author)
