Abstract

The paper describes a method for estimating the wing-body interference factor, Kw, for slender configurations, through subsonic, transonic, and supersonic speed ranges. It is shown that the method can predict Kw values for angles of attack up to about 30 deg. The factor Kw obtained by this method accounts for the effects due to the loss of upwash and to the decrease in dynamic pressure at higher angles of attack and Mach numbers. However, the method is limited to wings with aspect ratios less than 0.4 (typical of fins used in conventional missiles) with zero or small trailing-edge sweep angles
