Abstract : The Naval Ordnance Laboratory instrumented various Program 3 projects for pressure-time histories. The instrumentation system consisted of Wiancko inductance gages, FM intelligence generation, and magnetic tape data storage. Pressure measurements were made on three aboveground structures, one underground structure, five foxholes, a diffraction study layout around one of the aboveground structures, and a tree stand. The results of Shot 9 were excellent; 127 complete pressure-time records were obtained from the total of 128 stations instrumented. On Shot 10, 48 complete records and 48 partial records were obtained from the 105 stations instrumented. Broken cables caused by displacement of the structures accounted for most of the partial and total loss of records on this shot. The records were reproduced as pressure-time curves with pressure scales added and, along with instructions for record analysis and interpretation, were presented to the cognizant agencies for their analysis.
