FREE-AIR ATOMIC BLAST PRESSURE AND THERMAL MEASUREMENTS

Abstract

Measurements of blast overpressure and thermal radiation flux were carried out at high altitudes during both Mike and King shots of Operation Ivy by means of parachute-borne telemetering canisters. For each shot six canisters were dropped from each of two B-29 aircraft. Telemetered data were recorded from 10 of the 12 canisters at Mike shot and from 8 of the 12 canisters at King shot. When corrected for known altitude effects, the peak overpressures observed at high altitudes agree well with those measured on the ground except at extreme ranges, where the ground overpressure is relatively low. It is believed that this is due to upward refraction of the blast wave, which is to be expected at very low overpressures.
