A350 Fuselage


The new XWB fuselage will have a parallel cross-section width from door 1 to door 4, unlike previous Airbus aircraft to provide maximum usable volume. The double-lobe (ovoid) fuselage cross-section will have a maximum outer diameter of 5.97 m (compared to 5.64 m for the A330/A340). The cabin's internal diameter will be 5.61 m wide at armrest level (compared with 5.49 m of the 787 and 5.86 m of the 777).
In the eight abreast two-four-two arrangement, which is a premium economy layout, the seats will be 19.5 in (49.5 cm) wide between 2-in wide arm rests. Airbus claims that the seat width will be 0.5 in greater than the seat on the 787 in the equivalent configuration. In the nine abreast, three-three-three economy layout, the XWB's seat width will be 17.7 in which will be 0.5 in wider to the proposed equivalent seat layout for the Boeing 787.
Airbus confirmed in early September 2007 the adoption of composite fuselage frames for the aircraft structure. The composite frames will feature aluminium strips to ensure the electrical continuity of the fuselage (for dissipating lightning strikes). However, the fuselage crossbeams remain metallic, but Airbus is running trade-off studies to evaluate switching them to composite. The new design differs slightly from the 787 design which uses ovoid skin barrels on titanium ribs.
Airbus had signed a firm contract with BMW to have them develop an interior concept for the original A350.
