Project DUGOUT. Surface Motion Measurements

Abstract

Accelerometers and high-speed motion picture photography were used to measure the motion of the surface as it was thrown up by Dugout - a chemical row-charge cratering experiment in basalt, in which five 20-ton charges spaced 45 feet apart and at a depth of 59 feet were fired simultaneously. This report describes the experimental procedure for the surface motion measurements and gives the results obtained. Velocity profiles at various points on the rising "mound" of up thrown material from Dugout are presented and compared with those from another cratering experiment, Pre-Schooner Alpha, in which a single 20-ton chemical charge (equivalent to one of the five Dugout charges) was fired in the same basalt material as Dugout and at the same depth.
