Fin Dihedral Effects on Wing-Body Carryover for Supersonic Noncircular Missiles
Abstract
The aerodynamic effects of fin dihedral, Mach number, and fuselage cross section shape on wing-body carryover are investigated for supersonic, wing-body missiles at low angles of attack. A steady, three-dimensional, Euler code was used to numerically determine the normal force and center of pressure (CP) on infinitely thin delta wings in the presence of the missile body. The wing normal force is presented in terms of the component buildup parameter Kw(B), a measure of the wing-body interference due to body upwash. Kw(B) was found to be sensitive to dihedral, Mach number, and body cross-sectional shape. Fin dihedral influenced the wing CP for the inverted-triangular and triangular fuselage cross sections, but it did not appreciably affect the CP for circular, square, and diamond cross sections. For all fuselage cross sections, increasing Mach number moved the fin CP inboard. Changing the fuselage cross section from a circle to a diamond or triangle generally moved the fin CP outboard. © 1993 by the American Institute of Aeronautics and Astronautics, Inc.
