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 aerodynamic mean chord.
It is restricted to fully-attached subsonic flow and those
incidences where the lift-curve slope is essentially linear.

The effect on aerodynamic centre due to wing-pylon mounted
nacelles is obtained from ESDU 77012 and the effect due to
rear-fuselage pylon-mounted nacelles is obtained from ESDU
78013.

The computer program ESDUpac A1309, associated with ESDU 13009,
evaluates the chordwise position of the aerodynamic centre of
wing-fuselage-nacelle combinations at subsonic speeds.
