Project 1,2 ~- SURFACE PLAST MEASURHYENTS OF STATIC AND DYMAMIC
PRESSURSS = A. D. Thornbreugh
Carter D, Zroyles
This experinent was designed to neesure overpressure and dynauic
pressure vs time fran a surface burst of a medium yield (40 KT) nuclear
explosion,
Cvyerpressures wore measured with gages in ground baffles end
pitot-static tubes,
Dynamic pressures were measured with the pitot-
static tube mounted 3 feet above the ground surface,
The overpressures and dynenic pressures are in general agreenent
vith picwious picsurccomts of a 1 KT and of negaton Lursts, being con- “*
etsteant with v3 scaling snd a reflection factor of 1,6 using a free~
