Application of holographic interferometry to the exterior ballistic flow field in the muzzle environment of a twenty millimeter cannon
applicationofhol00bett.pdf (7.238Mb)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
(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
