The A350 XWB Family consists of three passenger versions with true long-range capability of flying up to 8,500 nm/15,580 km. The current paper deals the first Ground Vibration Test of the family done on the intermediate version (-900: 314 seats in a typical three-class configuration). The A350-XWB-900 is powered with two Engines RR Trent XWB (374 kN each one, 84,000 lbs each one) (Fig. 24.2). The A350 XWB brings together the very latest in aerodynamics, design and advanced technologies. Over 70 % of the A350 XWB weight efficient airframe is made from advanced materials combining composites (53 %), titanium and advanced aluminium alloys. The aircraft innovative all new Carbon Fibre Reinforced Plastic (CFRP) fuselage results in lower fuel burn as well as easier maintenance. From structural dynamics point of view, the vast number of innovations raised a big challenge by moving away from known structures. The A350 XWB final assembly has been thought out with efficiency in mind, in order to reduce the assembly time compared to current programmes and to enable a more effective test programme. Elements of the aircraft arrive at the A350 XWB assembly facility—located in Toulouse, France—already equipped and tested. Like a well-planned, high-technology puzzle, the jetliner then comes together through an optimised workflow that moves in steps through several stations within the integration building. As a full part of this streamlined process, GVT coming just before painting, it had to guarantee an optimised workflow fully integrated to the assembly line.
