Folding Wings Turn Boeing Jet Into A Fuel Saver
Boeing 777x boasts a gargantuan 233-foot wingspan to save on fuel costs
In an effort to lower the operating costs associated with fuel in the airline industry, Boeing has designed the new 777x, the first twin-engine jet able to haul a jumbo jet’s payload. What’s even more impressive is that it burns 12 percent less fuel than competing Airbus models, and 20 percent less than Boeing’s own 777-300ER. It achieves this with a new engine from GE Aviation and much longer composite wings that are able to fold up when the plane is taxiing through airports.
