Description/Abstract:
PRESSURE-TIME MEASUREMENTS ON TESTS DOG AND EASY WERE MADE IN THE MACH REGION BETWEEN 5 AND 100 PSI WITH A DIAPHRAGM-TYPE INDUCTANCE GAUGE A ND A SPRING-PISTON GAUGE. MEASUREMENTS WERE MADE AT CONSTANT HEIGHT A LONG A SINGLE RADIUS ON TEST DOG AND ALONG TWO DIFFERENT RADII FOR TES T EASY. IN ADDITION, DIAPHRAGM-TYPE INDUCTANCE GAUGES WERE INSTALLED AT FIVE DIFFERENT HEIGHTS ON APPROXIMATELY THE SAME RADII ON TEST EASY . FROM THESE DATA THE FOLLOWING BLAST PARAMETERS WERE OBTAINED: MAXIM UM PRESSURE, IMPULSE, AND DURATION, BOTH POSITIVE AND NEGATIVE; ARRIVA L TIME OF THE SHOCK; RISE TIME TO THE INITIAL MAXIMUM PRESSURE; TIME O F OCCURRENCE OF THE MAXIMUM PRESSURE; AND DECAY CONSTANT FROM THE MAXI MUM PRESSURE. THE DIAPHRAGM-TYPE INDUCTANCE-GAUGE MEASURING SYSTEM HA D AN ACCURACY OF 2 PER CENT IN PRESSURE AND A RESOLVING TIME OF APPROX IMATELY 1 MSEC. DATA WERE STORED ELECTRICALLY ON MAGNETIC RECORDING T APE. THE SPRING-PISTON GAUGE WAS A DIRECT-RECORDING MECHANICAL SYSTEM CAPABLE OF 5 PER CENT ACCURACY IN PRESSURE WITH A RESOLVING TIME OF 1 5 MSEC. COMPLETE DETAILS CONCERNING EQUIPMENT DESIGN, FIELD OPERATION , AND RECOMMENDATIONS FOR FUTURE USE OF THE SYSTEMS ARE PRESENTED.
