Air Blast Characterization: Impulse to Power

Abstract

Peak shock pressure (Pa) and positive phase duration (A-duration, s) reported by airborne blast pressure sensors are used to calculate the energy fluence (J/m2) on target. This energy fluence is then divided by shock overpressure duration (s) to yield an average shock power(W/m2) on target. A comparison is made to shock impulse (Pa asterisk s) calculated using similar reported data. A link between power of the explosive that created the airborne shock and power measured at target is shown.
