Abstract:

The four air-dropped, air-burst nuclear explosions of the TUMBLER tests during the spring of 1952 were conducted primarily to obtain definitive air pressure information. The earth acceleration measurements were designed to study the interaction between phenomena in the air and phenomena in the earth. The main objective was to estimate the magnitudes of the energy absorbed by the ground and the energy fed back into the air by the ground. Subsidiary objectives included a study of the effects of gage depth and the relative importance of the three acceleration components. This report is concerned with these objectives as obtained from many acceleration-time records of the vertical component, 5 ft deep a few records of the vertical component, 1 and 50 ft deep and a few records of the horizontal radial and horizontal tangential components, 5 and 50 ft deep.
