Abstract:

An experimental study of the effects of idealized topography on the dynamic pressure of a spherically expanding air shock is described. Modelscale techniques were used in which small charges of desensitized cyclonite were exploded in reduced ambient pressure to increase the effective weight of the charge through SACHSS SCALING. Model topographies studied were symmetrical, 2-dimensional ridges and valleys. Slope angles of 15 and 30 degrees and shock strengths of 2, 4, and 8 were examined. Measurements of stagnation, side-on, and dynamic pressure were made on the front and back slopes and in the flat region behind each modeled topography. Author
