Abstract:

An analysis was made of the relationships of surface motion to depth of burst COB for 1.7 gram, spherical charges of lead azide detonated in dry Ottawa sand. Surface motion was studied by taking high-speed movies of each test. A colored sand grid pattern was laid on the surface of the test bed, so the intersections of the pattern could provide the data points for study. The films were analysed by using a film reader for data reduction and computer programs for curve fitting. Relationships of velocity vs. DOB, ejection angle vs. DOB, ejection angle vs. velocity, and mound growth vs. time were studied.
