FREE-AIR AND FREE-FIELD BLAST PHENOMENA FROM A SMALL YIELD DEVICE

Abstract

The objectives were to record the overpressure and dynamic pressure versus time at selected distances along the surface as well as the overpressure versus time in free-air from the detonation of a subsurface, subkiloton nuclear device. The BRL self-recording gages and electronic recording systems were planned for both the surface level measurements and the free-air instrumentation which was suspended from a balloon. The balloon failed on D-1, and the free-air measurements planned by the project had to be cancelled. Based on the records obtained along the surface, it appears that the blast wave was nonideal from the 120 to the 260-foot station. The measured values fell below the predicted values from the 120 to the 560-foot station. The duration and impulse values also differed from predicted values from the 120 to the 260-foot station.
