On boattail bodies revolution having minimum wave drag

Keith C. Harder, Conrad Rennemann, Jr.
Aug 1955

The problem of determining the shape of slender boattail bodies of revolution for minimum wave drag has been reexamined. It was found that minimum solutions for Ward's slender-body drag equation can exist only for the restricted class of bodies for which the rate of change of cross-sectional area at the base is zero.
