 A Study of the Zero-Lift Drag-Rise Characteristics of Wing-Body Combinations Near the Speed of Sound by Richard T. Whitcomb

NACA-TR-1273 (1956), NTRS document 19930092271. The originating report abstract compares shock phenomena and drag-rise increments for wing/body combinations and equivalent bodies of revolution with matched axial area distributions. Indenting the body to compensate for the wing area reduced the measured zero-lift drag-rise increment. The reported conclusion is conditioned on thin low-aspect-ratio combinations near sonic speed; it is not a universal statement about every shape or Mach number.
