MEASUREMENT OF FREE-AIR ATOMIC-BLAST PRESSURES
Abstract
The objective of the project was to measure free-air peak overpressure and overpressure versus time vertically above an air burst of more than a megaton yield. These data were desired so that a comparison could be made between the overpressures actually observed and those calculated by various approximate methods of correcting for altitude effects. A vertical array of 12 parachute-borne, telemetering, blastpressure canisters was deployed by drop from a B-36 aircraft above intended ground zero for Shot Cherokee. Due to a large horizontal error in the actual point of burst, the array was not directly above the burst; 10 of the 12 canisters were in the free-air region, and two were below the path of the triple point in the Mach region. The range of altitude covered was 850 to 33,800 feet. Data were received from all units. (Author)
