This item calculates the shift at subsonic speeds in aerodynamic centre position, caused by mounting nacelles on short pylons on the rear fuselage of wing-fuselage combinations. The shift is calculated by treating the nacelles as annular aerofoils located in the wing downwash field and subject to nacelle-fuselage interference effects. The shift is then subtracted from the wing-fuselage aerodynamic centre position, calculated from item No. 76015, to provide the overall aerodynamic centre position of the wing-fuselage-nacelle combination. Rear-mounted nacelles cause a rearward shift in the aerodynamic centre position.
