Tompkins Robert E., White Kevin J., Oberle William F., Juhasz Arpad A. Traveling charge gun firings using very high burning rate propellants
Aberdeen Proving Ground, Maryland: Ballistic Research Laboratory, 1988. — 35 p.
A new class of experimental very high burning rate propellants (VHBR) has been formulated and studied for application toward the traveling charge concept. Combustion diagnostic work has been performed on various formulations to characterize the burning of these propellants under gun pressures. Results of the combustion diagnostics indicate that several of the VT-BR propellant formulations could be used as a traveling charge gun propellant. These diagnostic results were also used as propellant input parameters for a traveling charge computer model, XNOVAKTC. Gun firings were performed for both conventional and traveling charge configurations. Comparisons are presented between the experimental firings and the computer predictions. Results indicate that the traveling charge concept can offer increased performance over conventional systems provided that the ignition and burnout times of the traveling charge can be controlled.
