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.
