Boeing announces location of 777X Composite Wing Centre

Boeing : 23 February, 2014  (Company News)
Boeing has announced that its Everett, Washington site will be the location for a new composite wing centre for the 777X programme. It will be located north of the Everett factory. The new jets will be available in two variants, resized versions of the current 777-300ER, with "ultra-long range capability.
Boeing says the 777X will be both the largest and most efficient twin-engine jet in the world. "The airplane will build on the market-leading 777 and will provide superior operating economics," says Boeing Commercial Airplanes President and CEO Ray Conner. "The airplane will be 12 percent more fuel efficient than any competing airplane." A GE9X engine, built by GE Aviation, will contribute to overall fuel savings. The company has already received a reported 342 orders for the new aircraft. 
The new plane will also stretch the 777’s decades-old aluminium frame and update its pneumatic systems in lieu of the 787’s composite fuselage and all-electric architecture. Re-purposing proven technology lowers risk of production delays, a concern for customers after the Dreamliner debuted 3 1/2 years late in 2011, followed by a patchy performance in service. Production is due to begin in 2017. Commitments for the new jets already total over 340, though the first deliveries are not expected until 2020.
The 777X was launched with two siblings – the 777-9X and the 777-8X. Boeing states that the 9X will have a range of more than 8200 nautical miles (15,185 km) and the lowest operating cost per seat of any commercial airplane, whilst the 8X will offer a range of more than 9300 nautical miles (17,220 km). 
Boeing’s new-version 777 includes a swept-back airfoil wing designed in composite materials with increased thickness and a longer span than it has adopted for previous airliners, ensuring greater payload and range, improved takeoff performance, and a higher cruising altitude. Though much longer than current standard wing designs - based on those of the 787 Dreamliner and will stretch to 71m when extended, the new wings also will have a folding tip that will increase wingspan and, as a result, fuel efficiency without limiting access at airports. The wings also will serve as fuel storage areas, with longer-range models able to carry up to 47,890 gallons of fuel.
