Description/Abstract:
THE SPECIFIC OBJECTIVES OF PROJECT 1.1B INCLUDED THE DETERMINATION OF PRESSURE VS TIME VARIATIONS WITH GROUND RANGE, AT AND NEAR THE GROUND SURFACE, FOR FIVE NUCLEAR SHOTS DETONATED AT VERY HIGH, INTERMEDIATE, AND RELATIVELY LOW HEIGHTS OF BURSTS, AS WELL AS A LIMITED STUDY OF TH E NEAR-SURFACE UNDERGROUND ACCELERATIONS PRODUCED BY AIR BURST EXPLOSI ONS. USING THESE DATA, THE REPORT DISCUSSES AIR BLAST SCALING LAWS, M ACH REFLECTION (PATH OF THE TRIPLE POINT), PRECURSOR CHARACTERISTICS, THE EMPIRICAL HEIGHT OF BURST CHART, AND EARTH ACCELERATIONS. THE RES ULTS OF SOME EXPERIMENTS ON INSTRUMENTATION ARE INCLUDED AS APPENDIX B .
