PEAK OVERPRESSURE VS DISTANCE IN FREE AIR

Abstract

At the request of the Height Burst Panel, Project 6.13 was organized to make measurements on King Shot, Operation Ivy, that would establish the peak shock overpressure in the blast wave as a function of distance from the burst in the free air region. This information was required in particular to determine whether scaling laws could be used with existing data obtained on Operation Tumbler to predict free-air pressures from much larger weapons. Secondary objectives were to record and determine the magnitude of a precursor wave or other visibly observable thermal effects that might occur and to collect any additional information that might explain the departure of the free-air blast measurements obtained on Operation Greenhouse from the Operation Tumbler composite free-air pressure results. (The four free-air pressure-distance curves obtained on Operation Tumbler scaled very well over the entire pressure range measured. The composite result is considered to be highly reliable.)
