    Initial design

    In 2011, Boeing refined its response to the revamped Airbus A350 XWB with three 777X models, targeting a firm configuration in 2015, flying in late 2017 or 2018, and entering service by 2019. The 407–passenger 777-9X should stretch the 777-300ER by four frames to 250 ft 11 in (76.48 m) in length, for a 759,000 lb (344 t) maximum take-off weight (MTOW) and powered by 99,500 lbf (443 kN) engines, targeting per-seat 21% better fuel burn and 16% better operating cost. The smaller 353-seat 777-8X...

    Engine selection

    The General Electric GE90-115B of the earlier 777-200LR and -300ER variants has a 42:1 overall pressure ratio and 23:1 HP compressor ratio. Rolls-Royce Plc proposed its RB3025 concept with a 132 in (335 cm) fan diameter, a 12:1 bypass ratio, and a 62:1 overall pressure ratio, targeting a fuel burn of more than 10% lower than the GE90-115B and 15% lower than its Trent 800 powering the 777; the RB3025 concept has a composite fan, a core derived from the Trent 1000, and advanced HP materials. Pr...

    Launch

    In 2012, with the Boeing 737 MAX in development and the 787-10 launch in preparation, Boeing decided to slow 777X development to reduce the risk with introduction still forecast for 2019.On May 1, 2013, Boeing's board of directors approved selling the 353-seat 777-8LX to replace the 777-300ER from 2021, after the larger 406-seat -9X. The design work is distributed between Charleston, Huntsville, Long Beach, Philadelphia, St. Louis in the U.S and Moscow, Russia. Its developmentcost could be ov...

    Wing

    The 777X has a new longer composite wing with folding wingtips. Due to this, the 777x is the first aircraft to have 'Wingtip Controls' inside the cockpit. Based on the 787 wing but with less sweep, the new wing has a higher lift-to-drag ratio, aspect ratio increased from 9:1 to 10:1, area increased from 4,702 to 5,562 sq ft (436.8 to 516.7 m2), and usable fuel capacity increased from 320,863 to 350,410 lb (145,541 to 158,943 kg).Folding wingtips are a first for commercial aviation. To stay wi...

    Interior

    The internal cabin width is increased from the previous 777 models' 231 to 235 in (587 to 597 cm) through thinner interior cabin walls and better insulation to allow 18.0 in (46 cm) wide seats in 10-abreast economy. The 777X will feature cabin design details requiring structural changes that were originally introduced on the Boeing 787 Dreamliner: larger windows, higher ceilings, more humidity and lowered cabin altitude to 6,000 ft (1,800 m). Its flight deck is similar to the 787 cockpit with...

    Efficiency

    For the longer 777-9, new engines should improve fuel consumption by 10%, with the longer, carbon-fiber wings adding an estimated 7% improvement. As 4 to 5% of fuel savings is lost from the 12 tons heavier basic structure of the larger airliner, the net fuel efficiency gain is projected to be 12 to 13%. Ten-abreast seating instead of nine with a longer fuselage enable a reduction in fuel burn per seat of 20% compared to the 365-seat 777-300ER. The longer-range, 355-seat 777-8 should have a 13...

    777-8

    The 777-8 is a shortened derivative of the 777-9, 229 ft (69.8 m) long, between the 209 ft 1 in (63.7 m) 777-200 and 242 ft 4 in (73.9 m) 777-300. It would seat typically 384 passengers with a range of 8,730 nmi (16,170 km). It would succeed the ultra-long-range -200LR and compete with the Airbus A350-1000. Production of the -8 was expected to follow the -9 around two years later.It could be the basis of a freighter version which could be available 18 to 24 months after the introduction of th...

    777-9

    The 777-9 is stretched by three extra seat rows and flies 250 nmi (460 km) farther than the 777-300ER with the same weight. It is 9.4 ft (2.9 m) longer than the -300ER for a 251 ft 9 in (76.7 m) length. It will seat typically 426 passengers over a range of 7,285 nmi (13,500 km). Boeing froze its design in August 2015 and was to start first assembly in 2017. Its operating empty weight grew from the 777-300ER's 373,500 to 400,000 lb (169,400 to 181,400 kg), just over, for the -9 target.Listed a...

    777-10X

    Boeing is proposing to stretch the -9 by four rows of seats to accommodate 450 passengers in a 777-10X variant to compete with the Airbus A380 superjumbo. The company has approached several airlines including Emirates, the largest operator of both the 777 and the A380. The A380 seats between 489 and 615 passengers. The potential 263 feet (80 m) long 777-10X (12 ft or 3.7 m more) is competing against a hypothetical stretch of the A350-1000 for Singapore Airlines. Boeing confirmed that the stre...

    On September 19, 2013, Lufthansa became the first airline to select the 777X when it placed an order for 34 777-9 airliners, but the order was later changed to 20 firm orders and 14 options. In December 2013, Hong Kong-based Cathay Pacific ordered 21 777-9 airliners with deliveries expected from 2021,they will now not join Cathay's fleet before 202...
