CLOSE-IN TIME OF ARRIVAL OF UNDERWATER SHOCK WAVE,
Abstract
The close-in time of arrival of the shock wave from an underwater nuclear explosion on Operation Wigwam has been measured with good agreement between duplicate systems of electrical switches activated by shock pressure. The measurements extend from a distance of 15 to 2000 ft from the bomb, over a velocity range from approximately 130,000 ft/sec down to acoustic velocities such as 5000 ft/sec. Based on these measurements, the corresponding pressure-distance curve covers a range of 10 to the 5th power-fold from approximately 100 million psi down to 3000 psi. These data have been used to calculate the peak hydrodynamic variables at the shock front, and these calculations in turn permit a fairly complete description of the hydrodynamic variables on the interior of the wave. The weapon yield was calculated to be 31.7 = 1.2 kt. (Author)
