ESDU 76033 gives curves derived by correlating experimental data from a number of different sources enabling the base drag coefficient, based on body maximum cross-sectional area, to be predicted to within 0.025. Two-sets of curves are given, one for boat-tail angles below 16 deg and one for angles exceeding 16 deg; the drag depends on the ratio of base to maximum diameter, and boat-tail angle. The data were found to be independent of Mach number below 0.8 and it proved impossible to isolate any Reynolds number effects.
