Wing-Body Combinations With Certain Geometric Restraints Having Low Zero-Lift Wave Drag at Low Supersonic Mach Numbers

Abstract

Several variational problems involving optimum wing and body combinations having minimum wave drags for different kinds of geometrical restraints are analyzed. Particular attention is paid to the effect on the wave drag of shortening the fuselage and, for slender axially symmetric bodies, the effect of fixing the fuselage diameter at several points or even of fixing whole portions of its shape.
