"The A350 XWB is an all-new design offering a step-change
in lower seat mile costs requested by the market for its
next-generation of twin-aisle, long-range jetliners"
according to Airbus Industries' Le Bourget website, ref. below.
Several photos due to Airbus Industries are reproduced below but their is a very large selection
to be found in the reference 1. below
Over 70 per cent of the A350 XWB’s weight-efficient airframe is made from advanced materials, combining 53 per cent of composite structures with titanium and advanced aluminium alloys, the aircraft’s innovative all-new Carbon Fibre Reinforced Plastic (CFRP) fuselage also results in lower fuel consumption
KEY DESIGN FEATURES driving this improvement in economic efficiency are:
- the extensive use of lightweight composite materials for lower weight
and maintenance costs;
-the implementation of simple, efficient and
proven systems, including integrated modular avionics;
-the application of state-of-the-art aerodynamics; and the use of latest-generation engines with the lowest fuel consumption and reduced emissions.
REFERENCE 1. A350 XWB FAMILY:- Technology and Innovation
The A350 XWB has been designed to be eco-efficient from gate to gate ie. lower noise and fewer emissions at every single stage of the journey:
-1. It brings together the very latest in aerodynamics, design and advanced technologies in the A350 XWB to provide a 25 per cent step-change in fuel efficiency compared to its current long-range competitor.
-2. Contributing to this performance are the Rolls-Royce Trent XWB engines that power the A350 XWB Family.
As over 70 per cent of the A350 XWB’s weight-efficient airframe is made from advanced materials, combining 53 per cent of composite structures with titanium and advanced aluminium alloys, the aircraft’s innovative all-new Carbon Fibre Reinforced Plastic (CFRP) fuselage also results in lower fuel consumption.
Simply put, every tonne of fuel saved means more than 3 tonnes of CO2 avoided, and the A350 XWB’s eco-efficient operation ensured margins for both current and future international environmental protection regulations.
The A350 XWB design favours environmentally-friendly materials in the manufacture of the aircraft.
1. Replacing the standard chrome-plating process with a more environmentally-friendly thermal spray alternative. This dry process produces a dense metal coating, which gives the same properties as chrome plating – including wear resistance, corrosion resistance, low oxide content, low stress, low porosity, and high bonding strength to the base metal.
2. The painting of A350 XWB's in airline colours uses an environmentally-friendly, chromate-free primer paint. Also following best practices from the auto industry, Airbus will use a new base coat/clear coat system that requires less paint and less solvent. This eco-efficient painting process also means that less detergent will be needed when washing the aircraft. Inside, the jetliner, Airbus will use, wherever possible, water-based paint – one of the most environmentally-friendly types of paint available.
