A derivation, on a theoretical basis, of the physical characteristics of a class of ring-body configurations. It is shown that, relative to a Sears-Haack body of fineness ratio 15, on a drag-per-unit-volume basis there is a large four-dimensional space, of Mach number, central-body fineness ratio, ring radial-position parameter, and percent extent of laminar flow, for which the potential drag reduction is large.
