Zusammenfassung:This report presents free field blast data obtained by instruments positioned at selected distances from the center of a 500-ton hemispherical surface charge of TNT. Measured values of shock arrival time, overpressure, duration of positive phase of the shock wave, impulse, and dynamic pressure are plotted as functions of distance and are compared with predicted values. Pressure-time histories obtained at pressure levels of 300, 90, 30 and 15 psi are compared with predicted wave shapes. Measured data in the low and moderate pressure regions compare favorably with predicted values.
