TRANSIENT DRAG LOADING OF ACTUAL AND IDEALIZED SHAPES FROM HIGH-YIELD DETONATIONS

Abstract

Investigation of aerodynamic-drag characteristics by measurements on full-scale I beams (8WF67) and angle irons (8L56.9) were made at various pressure levels from Shot Cherokee. Drag and lift coefficients were obtained although the flow was not normal to the beams. Resolution of the flow was determined. A description of an experiment for determining drag coefficients for spherical shapes as a function of the dynamic pressure of the flow following blast wave fronts is given. Two sizes of spherical shell (3 and 10 inch diameter) were used in conjunction with three-dimensional, force-sensing mechanisms. The sensing mechanisms and calibration procedure are described.
