Description/Abstract:
CHAPTER 11 REPORTS ON THE FREE-PISTON GAUGES USED TO MEASURE THE PARAM ETERS OF THE AIR SHOCK WAVE AT VARIOUS DISTANCES FROM THE POINT OF DET ONATION. THIS GAUGE CONSISTS OF A PISTON, FREE TO MOVE WITH NO RESTORI NG FORCES, AND ACTED UPON AT ONE END BY THE SHOCK WAVE WHICH RECORDS A SPACE-TIME CURVE, I.E., A DISTANCE-VERSUS-TIME CURVE OF THE PISTON'S MOVEMENT. A DESCRIPTION OF THE INSTRUMENT AND A METHOD OF ANALYZING T HE RECORDS ARE PRESENTED, TOGETHER WITH AN EVALUATION OF POSSIBLE ERRO RS IN THE MEASUREMENTS. CHAPTER 12 COVERS AIR BLAST PRESSURE MEASUREME NTS MADE DURING X-RAY, YOKE, AND ZEBRA SHOTS AT VARIOUS DISTANCE FROM THE BOMB. THE MEASUREMENTS CONSISTED OF THE RECORDING OF PRESSURE ON A TIME BASE BY MEANS OF DIAPHRAGM BLAST GAUGE CHANNELS. THE GAUGE CONS ISTS ESSENTIALLY OF A SMALL, FIXED-EDGE DIAPHRAGM IN WHICH DEFORMATION DUE TO PRESSURE ARE TRANSFORMED INTO CHANGES OF ELECTRICAL RESISTANCE . THE INSTRUMENTATION, CONSISTING OF THE GAUGE, CARRIER-TYPE AMPLIFIER AND RECORDERS, AS WELL AS THE POWER SYSTEM, IS DESCRIBED. CHANGES MAD E IN THE INSTRUMENTAL SETUP AFTER THE INITIAL TEST ARE DISCUSSED.
