Combustion Diagnostics and Ballistic Results of Proposed Traveling Charge Propellant

摘要

Experimental studies, including high pressure closed chamber combustion tests and gun firings, were performed on a series of propellant formulations containing a boron hydride salt. Samples consisted of a Kraton binder, RDX oxidizer and boron hydride fuel. Booster-aided combustion tests using a specially designed closed bomb fixture indicated that these samples could exhibit desired burning properties for a traveling charge propellant application. Gun firings indicate that with adequate ignition control it is possible to tailor the gun pressure-time profiles in the desired direction to increase down-bore acceleration and demonstrate the traveling charge effect.
