MECHANICAL IMPULSE MEASUREMENTS CLOSE TO EXPLOSIVE CHARGES
Abstract
A mechanical plug gage is used for measuring "face-on" impulse in air blast close to spherical Pentolite explosives detonated in air at different ambient pressures. The data are compared with previous results. The study indicates that at small distances (z<1.5 (ft/[cu.rt.lb]) the change in normally reflected impulse with variation in ambient pressure is negligible; it further suggests that the measured impulse, within several charge radii, of the explosive is due to the flow of the explosion gases and that the interchange of impulse between positive and negative phases is small.
