Drag Coefficients for Irregular Fragments

Abstract

Drag coefficients for irregular fragments were determined for 96 fragments in a vertical wind tunnel at Mach numbers of approximately 0.1. Correlation of drag coefficient with the maximum-to-average presented area ratio is presented. A method for approximating the whole drag curve is also given. Physical characteristics, photos, and wind tunnel test results are given in the appendixes. Keywords: Irregular fragments; Drag coefficient; Vertical wind tunnel; Correlation. (JHD)
