Blast Measurements On A Medium-Yield Surface Burst

Abstract

Overpressure and dynamic pressure were measured as a function of time and distance (690 to 3,250 feet) on a surface burst of a medium yield (40 kt) nuclear device on Site Yvonne, Eniwetok. Overpressures were measured with ground baffles and pitot-static gages. A precursor formed but died out at an unusually high overpressure of between 35 and 55 psi. The usual high dynamic pressures associated with precursors were observed. Outside of the limited region in which the precursor existed, the overpressure and dynamic pressure measurements were in agreement with previous measurements on surface bursts. They were consistent with the freeair values for 1.6 times the actual yield of 39.5 kt. (Author)
