Boeing 777-9X, The World's Largest Twin Engine Jetliner

Description of Boeing 777-9X

The Boeing 777 is the first aircraft fully designed digitally using 3D computer graphics that eliminates the need for expensive full-scale mock-ups. The result is airplanes larger than all other twin-engine and tri-engine aircraft and smaller than Boeing 747 aircraft while intended for medium and long-term markets and bring the low cost benefits of twin-engine aircraft.

The Boeing 777-9X is the first aircraft of the 777 generation to become the world's largest twin-engine jetliner. The Boeing 777-9X has the widest wingspan of all aircraft in the company's 102-year history. The wing tips of the Boeing 777-9x have hinges with locking pins, so that the wing tips can be folded. The wing gave an additional jetliner ride, similar to a giant aircraft launcher, helping Boeing 777-9X aircraft to save 12% more fuel than the Airbus A350.

The fuselage is made of aluminum, like most airplanes, but its wings are made of carbon fiber which is very strong and lightweight, which helps save fuel. (That is why the wings are very flexible.) A special process for making wings is needed, including a large special pressure oven for baking carbon fiber materials. The wingspan is 235.5 feet large or 71.7 meters, which is the widest aircraft of all that has ever existed in the Boeing range. The folding wing tip will allow a span of seven meters more to maximize fuel efficiency.

The Boeing 777-9X will debut in 2020, with flight testing starting in 2019. This aircraft can accommodate capacity of 350 to 425 passengers with operating costs 10% lower than the A350-1000. The distance that the aircraft can reach is estimated at more than 14,000 kilometers (8,699 miles). The upcoming 777-9X is Boeing's best opportunity to win the challenge of the 'Sunrise Project' from Qantas. The airline wants a plane that can fly from the eastern capital of Australia to London and New York without stopping. Airbus rivals believe the long distance aircraft, the A350-900ULR, can be adapted to make that distance.

Several airlines including Emirates, All Nippon Airways and Lufthansa have ordered Boeing 777-9X aircraft. Boeing's new X family is present as part of a technical revolution that allows jet aircraft with only twin-engine to travel the same global route routes as larger, fuel-guzzling four-engine airliners such as the 747 and Airbus A340 and A380 Super Jumbo.
