777X to deliver unprecedented efficiency and economics: Boeing

Boeing, one day after announcing the record-breaking launch of the 777X, outlined (18-Nov-2013) the performance characteristics and a variety of features "that will make the newest member of the Boeing twin-aisle family the largest and most fuel-efficient twin-engine commercial jetliner in aviation history". Boeing noted that key innovations will make the 777X 12% more fuel efficient than its competitor, through the following features: an all-new composite wing based on the wing developed for the 787, aerodynamic advances such as a hybrid laminar flow control vertical tail and natural laminar flow nacelles, and all-new GE9X engines developed by GE Aviation. Boeing also said these new technologies will help the 777X deliver 10% lower operating economics than the competition. Boeing Commercial Airplane VP and GM of airplane development Scott Fancher said, "The 777X builds on the heritage of the 777-300ER and incorporates many advanced technologies designed for the 787 to create a new standard for widebody airplanes. It will truly be a worthy successor to the 777-300ER". Two models comprise the 777X family - the 777-8X, with approximately 350 seats and a range capability of more than 9300 nautical miles; and the 777-9X, with approximately 400 seats and a range of more than 8200 nautical miles. The 777-8X competes directly with the A350-1000 while the 777-9X is in a class by itself, according to Boeing. At 233 feet, the 777X composite wing has a longer span than today's 777-300ER. Its folding, raked wingtip delivers greater efficiency, significant fuel savings and complete airport gate capability, Boeing noted, adding that it allows access to the entire range of gates currently accessibly by the 777-300ER. Adding 787 technologies in the flight deck, flight controls and other systems is just the beginning. The 777X implements 787 technologies where they add value to our customers and increase commonality across Boeing's twin-aisle product family. Boeing also said it is exploring a number of innovations that will advance the passenger experience and create an interior passengers will prefer. For instance, the company will reposition and resize the windows to provide more ambient light inside and provide passengers with better views outside the cabin. A new interior architecture will make the 777X cabin even more spacious, leveraging the airplane's cross-section which is the widest in its class. The 777X is targeted for first delivery in 2020.
