Validation Tests in Building 327 - 50-Pound Bombproof
Abstract
This report presents the results of a group of validation tests conducted on the new 50-pound blast chamber, NSWC/WO Building 327. An initial series of nine shots, ranging in weight from 1 to 50 pounds of TNT, were fired. (Subsequently, two additional shots, weighing 20 to 43 pounds of TNT, were also fired. These two additional shots are also partly reported herein.) Measurements were made on chamber wall displacement, strain levels in the chamber walls, floor motion in work area, sound levels both in the work area and outside the building, and carbon monoxide levels in the work area. It was found that charges weighing 30 pounds or more produced high concentrations of carbon monoxide in the work area. Sounds levels in the control room were no higher than 115 dB peak flat sound pressure level. Pressure levels outside the building were also in the acceptable range. The floor motion seemed to go through a resonance of between 40 and 80 Hz, depending on the charge size. The quassi-static pressure levels agreed well with predicted values. Keywords: Explosion Testing, Quasi-Static Pressure, Explosion Effects.
