The Airbus A350 is a long range, mid-sized, wide-body family of
airliners currently under development, designed to compete with the Boeing 777and Boeing 787. The A350 will be the first Airbus with fuselageand wing structures made primarily of carbon fiber reinforced plastic. [http://www.eads.com/xml/content/OF00000000400004/7/19/41508197.pdf Taking the lead: A350XWB presentation] " EADS"] It is scheduled to enter into service in 2013.
Boeingannounced its 787 Dreamliner project, it claimed the lower operating costs of this airplane would make it a serious threat to the Airbus A330. Publicly, Airbusinitially rejected this claim, stating that the 787 was itself just a reaction to the A330, and that no response was needed to the 787.
The airlines pushed Airbus to provide a competitor, as Boeing had committed the 787 to have 20% lower fuel consumption than today's equivalent types. Initially Airbus proposed a simple derivative of the A330, unofficially dubbed the 'A330-200Lite', with improved aerodynamics and engines similar to those on the 787. The airlines were not satisfied and Airbus committed €4 billion to a new design to be called the A350. The original version of the A350 superficially resembled the A330 due to its common
fuselagecross-section and assembly. A new wing, engines and a horizontal stabilizer were to be coupled with new composite materials and production methods applied to the fuselage to make the A350 an almost all-new aircraft.
16 September 2004, then Airbus president and CEO Noël Forgeardconfirmed that a new project was under consideration, but did not give a project name, and would not state whether it would be an entirely new design or a modification of an existing product. Forgeard indicated that Airbus would finalise its concept by the end of 2004, begin consulting with airlines in early 2005, and aim to launch the new development programme at the end of that year.
10 December 2004the boards of EADSand BAE Systems, then the shareholders of Airbus, gave Airbus an "authorisation to offer (ATO)", and formally named it the A350." [http://news.bbc.co.uk/2/hi/business/4085631.stm Airbus to launch Boeing 7E7 rival] ." BBC News. 10 December 2004.]
6 October 2005full industrial launch of the program was announced with an estimated development cost of around € 3.5 billion. This version of the A350 was planned to be a 250–300-seat twin-engined wide-body aircraftderived from the design of the existing A330. Under this plan, the A350 would have modified wings and new engines while sharing the same fuselage cross-section as its predecessor. Controversially, the fuselage was to consist primarily of Al-Li, rather than the CFRPfuselage on the 787. It was to see entry into service in 2010 in two versions; the A350-800 capable of flying 8,800 nautical miles (16,300 km) with typical passenger capacity of 253 in 3-class configuration and the 300-seat (3-class) A350-900 with 7,500 nautical mile (13,890 km) range. It was designed to be a direct competitor to the 787-9, and 777-200ER.
Almost immediately Airbus faced criticism on the A350 project by the heads of two of its largest customers, ILFC and GECAS. On
28 March 2006, in the presence of hundreds of top airline executives, Steven F. Udvar-Hazy, of ILFC lambasted Airbus' strategy in bringing to market what they saw as "a Band-aid reaction to the 787," a sentiment which was echoed by GECAS president Henry Hubschman. Udvar-Hazy called on Airbus to bring a clean-sheet design to the table, or risk losing most of the market to Boeing."

Several days later, similar comments were made by
Chew Choon Seng, CEO of Singapore Airlines. Chew stated, "having gone to the trouble of designing a new wing, tail, cockpit" and adding advanced new materials, Airbus "should have gone the whole hog and designed a new fuselage.""

14 June 2006, Singapore Airlines announced it had selected the 787 over the A350, ordering 20 787-9s. [http://boeing.com/news/releases/2006/q2/060614b_nr.html Singapore Airlines 787 Dreamliner Announcement] Press release] Emirates Airlinedecided against making an order for the initial version of the A350 because of weaknesses in the design." [http://news.independent.co.uk/business/news/article1090115.ece Pressure mounts following attack by Emirates] ." Brierley, D. The Independent. 18 June 2006.]
As a result of these criticisms, in mid-2006 Airbus undertook a major review of the A350 concept. The proposed new A350 was to become more of a competitor to the larger
Boeing 777as well as some models of the Boeing 787, with a larger fuselage cross-section able to accommodate 9 passengers per row in a high-density configuration. The A330 and previous iterations of the A350 would only be able to accommodate 8 passengers per row in normal configurations. The 787 can accommodate 8 or 9 passengers per row, while the 777 can accommodate 9 passengers per row (in a small proportion of their 777 fleet, these airlines seat 10 passengers abreast: Emirates, KLM, and China Southern). From the point of view of a seated passenger, the A350 cabin is 13 cm (five inches) wider at eye level than the competing Boeing 787, and 28 cm (eleven inches) narrower than the Boeing 777, its other competitor. All A350 passenger models will have a range of at least 8,000 nautical miles(15,000 km).
There was some speculation that the revised aircraft would be called the Airbus A370 or A280, with Airbus going as far as accidentally publishing an advert referring to the aircraft as the "A280" on the "
Financial Times" website. However, on 17 July 2006, at the Farnborough Airshow, Airbus announced that the redesigned aircraft would be called A350 XWB (Xtra Wide-Body).
Airbus achieved its first sale of the redesigned A350 four days after its unveiling when
Singapore Airlinesannounced an order for 20 A350 XWBs with options of a further 20. Its CEO, Chew Choon Seng, said in a statement, that "it is heartening that Airbus has listened to customer airlines and has come up with a totally new design for the A350."

Flight International" December 2006] With an area of 443 m² (4,740 ft²) it will be the largest wing ever produced for a single-deck widebody aircraft. The geometric wingspanof 64 m (210 ft) is 3.7 m greater than that of the A330 and the original A350. The current biggest twinjet wing belongs to the long-range Boeings 777-200LR/777-300ER, which have 0.7 m greater span but slightly less area. The new wing will have 35 degrees of sweep (5 degrees more than the A330) helping to increase typical cruise speed to Mach 0.85 and maximum operating speed to Mach 0.89.
Airbus is currently working on the detail of the wings'
aerodynamicsand it will not freeze the final configuration until the October 2008 design freeze milestone. A new trailing-edge high-lift system has been adopted with an advanced dropped hinge flap (similar to that of the A380) which permits the gap between the trailing edge and the flap to be closed with the spoiler.

The new nose will improve aerodynamics and enable overhead crew rest installed further forward and eliminate any encroachment in the passenger cabin. The new windscreen has been revised to improve vision by reducing the width of the center post. The upper shell radius of the nose section has been increased.
The nose is likely to be constructed from aluminium but Airbus is currently running trade-off studies considering one-piece carbon fiber structure. According to Gordon McConnell, A350 Chief Engineer, a carbon fiber structure would need titanium reinforcements for birdstrike protection, thus the aluminium structure is the best cost-wise.

Fuel and hydraulic systems
Parker Aerospacehas been selected to supply the complete fuel package, which include inerting system, fuel measurement and management systems, mechanical equipment and fuel pumps. The fuel tank inerting system will feature air-separation modules to generate nitrogen-enriched air that will be used to reduce the flammability of fuel vapour in the tanks.
The company will also provide hydraulic power generation and distribution system. The work packages cover the reservoirs, manifolds, accumulators, thermal control, isolation, software and a new engine- and electric motor-driven pump designs. Parker Aerospace estimates the contracts will generate more than US$2 billion in revenues over the life of the programme.

Airbus has adopted a completely new philosophy for the attachment of the A350 XWB’s main
landing gearas part of the switch to a composite wing structure. Each XWB's main landing gear leg is going to be attached to the rear wing spar forward and to a gear beam aft, which itself is attached to the wing and the fuselage. To help reduce the loads further into the wing, a double side-stay configuration has been adopted. This solution resembles the design of the Vickers VC10.

Airbus devised a three-pronged main landing gear design philosophy encompassing both four- and six-wheel bogies to ensure it can keep the pavement loading within limits. The A350-800 and A350-900 will both have four-wheel bogies, although the -800's will be slightly shorter to save weight. Both will fit in the same 4.1 m (13.5 ft) long bay. The proposed higher weight variant, the A350-1000, A350-900R (Airbus is offering BA a variant called the A350-900R, which will have a range of about 9,400 nautical miles. This would allow the airline to schedule direct Heathrow-to-Sydney flights.) and A350-900F will use a six-wheel bogey and a 4.7 m landing gear bay.

There are three variants of the A350 and all launched in 2006. The A350-900 is scheduled to enter service in 2013. The A350-800 is scheduled to enter service in 2014. The last model to enter service will be the A350-1000 scheduled in 2015.
The A350-800 will seat 270 passengers in a 3-class cabin and will have a range of 8,300 nmi (15,400 km). It is designed to compete with the
Boeing 787-9and to directly replace Airbus' own A330-200.
The A350-900 is the first model scheduled to enter service (EIS) in 2013 and seats 314 passengers in a 3-class cabin 9-abreast layout. The aeroplane will have a range of 8,100 nmi (15,000 km). Airbus claim that the A350-900 will have a decrease of 16% MWE per seat, a 30% decrease in block fuel per seat and 25% better cash operating cost against the Boeing
777-200ER[ [http://leeham.net/filelib/Leahy_Final.pdf John Leahy presentation at Paris Le Bourget 2007 Air Show] " Airbus"] .
