The forward shift in aerodynamic center caused by mounting nacelles on pylons below the wings of wing-fuselage combinations of medium-to-high aspect ratio is calculated, for subsonic speeds, by treating the nacelles as annular aerofoils located in the wing upwash field. This shift is subtracted from the wing-fuselage aerodynamic center position, calculated from Item No. 76015, to provide the location of the overall aerodynamic center of the wing-fuselage-nacelle combination at cruise conditions.
