Boeing touts advances in 777X

US airframer Boeing (NYSE: BA) has outlined the performance characteristics and a variety of features on its 777X variant that is the newest member of the Boeing twin-aisle family.

According to Boeing, key advances will make the 777X 12% more fuel efficient than its competitor.

The aircraft features an all-new composite wing based on the innovative wing developed for the 787 Dreamliner, and aerodynamic advances such as a hybrid laminar flow control vertical tail and natural laminar flow nacelles.

Boeing said that the 777X will also have all-new GE9X engines developed by GE Aviation (NYSE: GE).

Two models comprise the 777X family the 777-8X, with approximately 350 seats and a range capability of more than 9,300 nautical miles; and the 777-9X, with approximately 400 seats and a range of more than 8,200 nautical miles. The 777-8X competes directly with the Airbus A350-1000 while the 777-9X is in a class by itself, serving a market segment that no other airplane can.

At 233 feet, the 777X composite wing has a longer span than the current 777-300ER.

Its folding, raked wingtip delivers greater efficiency, significant fuel savings and complete airport gate capability, Boeing said. In addition, it allows access to the entire range of gates currently accessibly by the 777-300ER.
