AIR BLAST MEASUREMENTS ABOUT EXPLOSIVE CHARGES AT SIDE-ON AND NORMAL INCIDENCE

Measurements of air blast peak pressures, positive impulses, and positive durations for both side-on and normal incidence from bare 50/50 spherical pentolite charges are presented. The explosive weight ranged from 1/2 to 6 pounds, the scaled distance from 1.46 to 14.61 ft/lb/sup 1/3/. Results of two hundred and sixty-nine test firings are tabulated and presented graphically. A description is given of the piezoelectric gage developed to measure the blast in the normally incident waves. (auth)
