MIMIMUM-DRAG BODY WITH SPECIFIED CENTER OF PRESSURE.

Abstract

A body profile is found that minimizes the zero-lift, Newtonian pressure drag of slender bodies of revolution when the center of pressure for small incidence is a specified percent of body length. Other constraints considered are those on body length, diameter or volume. The zero-lift drag is shown to increase when a constraint on center of pressure location is added to two of the other constraints, and the optimal profile is shown to be inflected when the center of pressure lies between 62.2 and 75 per cent of the body length.
