Abstract : The specific impulse of an explosive-plate system was calculated using a one-dimensional hydrodynamic computer code. Parameters affecting the delivered impulse, including charge-to-mass ratio, explosive composition, plate material, and stand-off distance, were varied. Calculations were compared to available experimental data which verified their accuracy. The computed impulse from conventional military explosives was less than 250 seconds. Increased efficiency resulted from the use of a nozzle which produced an impulse of approximately 270 seconds and from a high energy, aluminized explosive model with an impulse of 321 seconds.
