FREE-AIR ATOMIC BLAST PRESSURE MEASUREMENTS
Studies were made to determine the free-air peak overpressure vs. distance curve for air bursts at overpressure below those covered by existing data, the path of the triple point at high altitudes, and the relative strengths of the free-air and reflected shocks above the triple point and of tbe Mach shock below the triple point. The free-air values have been normalized to 1 KT in a homogeneous sea-level atmosphere and used to extend the Tumbler composite free- air curve down to overpressures of approximately 0.97 psi. A comparison of this curve witb the results of previous tests at low heights of burst has been made to determine the effective reflection factor for these earlier shots. Some tentative conclusions were reached on the distribution of peak overpressures in the reflected and Mach shocks in the neighborhood of the triple point. (auth)
