Hypervelocity Firings from a 7-Inch HARP Gun
Abstract
Numerous approaches are being pursued to launch projectiles of various types to hypervelocities. While much recent activity has focused on the development of electric guns, research is also being conducted employing conventional chemical propulsion, both to provide a detailed understanding of the hydrodynamics of conventional hypervelocity launchers and to provide baseline data against which the various emerging propulsion concepts can be evaluated. Over the past several years, firing were conducted at the Ballistic Research Laboratory using long 120-mm gun tubes to provide velocities in the 2. 5-2.7 km/s range. This report documents more recent, limited firings using a 7- inch HARP gun, launching 5-kg projectiles to a velocity exceeding 2.8 km/s. Simulations of these firings were made using the XNOVAKTC (XKTC) interior ballistic code, and a comparison of theoretical and experimental data is provided.
