THE MEASUREMENT OF FREE AIR ATOMIC BLAST PRESSURES
Shock overpressure as a function of time was measured by utilizing an array of parachute-borne pressure gages spread over a wide range of distances and altitudes above two atomic detonations. The data were telemetered from the balloons and recorded at a ground station. Three multiple object tracking stations were used to locate the position of each parachute. The observed peak overpressures covering the range from about 0.1 to 3.0 psi confirmed existing theory on the effect of altitude on shock overpressure to within practical accuracy requirements and supplemented other free-air peak overpressure measurements which were made at higher overpressures by other methods. Meteorological data for Snapper Bursts 2 and 5 are given. Recommendations for future tests are included in the report. (auth)
