Description/Abstract:
MEASUREMENTS WERE MADE TO DETERMINE THE DIFFERENCE IN BLAST EFFECTS OV ER A SURFACE COVERED WITH LOW SHRUBS AND GRASS AND OVER A CLEARED SAND Y SURFACE IN THE PRECURSOR REGION, AND AN ATTEMPT WAS MADE TO CORRELAT E THIS DIFFERENCE WITH MEASUREMENTS OF PRESHOCK SOUND SPEED OVER THE S URFACE. OVERPRESSURE WAS MEASURED WITH GROUND-BAFFLE GAGES AND WITH P ITOT-STATIC GAGES AT 3-FOOT ELEVATION. DYNAMIC PRESSURES WERE MEASURE D AT THE 3-FOOT ELEVATION WITH THE PITOT-STATIC GAGES. MEASUREMENTS W ERE MADE AT THE SAME GROUND RANGES FOR VEGETATED SURFACE AS FOR THE SA NDY SURFACE. THE VEGETATION REDUCED THE SEVERITY OF THE PRECURSOR, SH OWING LATER ARRIVAL TIMES AND SMALLER DYNAMIC PRESSURES THAN OVER THE CLEARED AREA. THE OVERPRESSURES OVER THE VEGETATION WERE THE SAME AT THE GROUND AND 3-FOOT LEVELS. NO MEASUREMENTS OF SOUND SPEED AFTER ZE RO TIME WERE OBTAINED, SO A CORRELATION IS NOT POSSIBLE.
