Summary

[edit]
Description 330-PSA-134-60 (USN 1049123): 22-Decree Blast Cone. William S. Filler, a Naval Ordnance Laboratory Physicist, adjusts one of the pencil-type piezo-electric cages which are fitted into a 22-degree cone to measure shock waves. The cone was designed to amplify an explosive blast 110 times. Test results from this cone and a 2-degree cone show that it is feasible to utilize the blast cone method to study shock waves as powerful as those generated by the Hiroshima Atomic Bomb which was equal to 20-thousand tons of TNT. Photograph released August 1, 1960. (8/25/2015).
