Everything about Boeing 777X

the 777Xs should be more appealing to passengers, which promotes larger windows, a wider cabin, new lighting and new architecture among the main features to lure customers.

Key elements of the future Boeing 777X

When parked at the gate, the Boeing 777X would have the same wingspan as the second-generation counterparts. The significantly increased wingspan will only be utilised as the 777X taxis to the runway and the tips of the huge wings unfold.

The inflight wingspan technology provides a new chapter in commercial aviation history. The aircraft’s wing tips can be folded up to increase the wingspan from 64.8 m, when the aircraft is on the ground, to 71.8 m during the flight. This allows the mammoth aircraft onto taxiways or into regular gates.

Meanwhile, the extended wingspan comes handy off-ground, as they allow to increase lift capacity and maximize fuel efficiency. Whilst aircraft with folding wings is not unheard of in aviation, the Boeing 777X is the first passenger aircraft with this feature. Aircraft with folding wings are already in use, even with Boeing military aircraft that operate from aircraft carriers, such as the Boeing F/A-18E/F Super Hornet.

The Boeing 777X will be powered by two General Electric (GE) GE9X engines, built exclusively for the latest version of Boeing’s long-haul wide body. The engine is developed on the foundations of the GE90, which powers the earlier versions of Boeing 777. Launched in 2013 and according to GE, the GE9X engine will be the most fuel-efficient jet engine the company has ever produced on a per-pounds-of-thrust basis. When it enters service with the 777X, power plant, which is roughly the size of a 737’s fuselage, will be the largest commercial jet engine available.
