ABSTRACT	ESDU 76015 gives an empirical method for correcting the wing-alone aerodynamic centre position from ESDU 70011. Graphs give correction factors for fuselage forebody and afterbody length, and width, and fuselage height/width ratio. An equivalent wing is used, extending the net wing into the fuselage, and the method can be applied to wings with cranks (see also ESDU 76003). The method was derived from data from 32 configurations of aspect ratio 6 to 12, mid-chord sweeps up to 45 degrees, and taper ratios of 0.2 to 1 and it predicts the position to within 0.03 of mean aerodynamic chord. It is restricted to fully-attached subsonic flow and those incidences where the lift-curve slope is essentially linear.
