A Boeing 777 airplane has been redesigned to be more aerodynamic and more efficient, but a former 747-400C plane still holds the record for the largest aircraft to be built in the United States, according to a new design from aerospace company Aerojet Rocketdyne.
The 777X is the world’s largest aircraft, and its design is based on a Boeing 777-200ER.
It’s also the world champion for the smallest airliner.
“I think the 777X and its engine are one of the most powerful engines ever made, so it’s a lot more capable than the 737,” said John Egan, vice president of aeronautics and space for Aerojet.
The design is a result of the Boeing 777X’s design changes over the years, Egan said.
It took years for Aerojets engineers to find a way to use the 777’s engine to improve efficiency, but the engine’s shape has changed.
“The 777 is actually a very large aircraft,” Egan explained.
“The wings have been extended, and the fuselage has been extended.
And so, the 777 was designed to be able to do that.
So, in some ways, it’s more aerodynamically efficient than the 747.”
The design also uses a “bulkhead” fuselage that’s nearly 50% more powerful than a 747-200, Egon said.
That’s a big improvement over the 777, which is built on the same 787-9 Dreamliner platform as the 737.
The 737X has the largest wing area in the world, Eagan said.
The 777X has wings that measure about 4% bigger.
“It’s a very, very good airplane,” Egon told ABC News.
“It’s got a really good, very large wing area.
The biggest wing area we’ve ever seen.
So we can really, really see the potential for it to do an incredible amount of lift.”
Egan said the 777 is a much smaller aircraft than the 777.
The 787 is 5.5 meters (16 feet), the 777 has a wingspan of 7 meters (21 feet).
Egan and his team took the 777 out for a test flight earlier this month, and it was able to climb to speeds of up to Mach 2.5 and climb to an altitude of 6,000 meters (back in 2001), Egan told ABCNews.
It has a top speed of up 100 kilometers per hour (62 mph).
Egon and his colleagues also designed a new, lighter fuselage and modified the engine to achieve higher lift, Egal said.
“We got the design down to about 6,800 kg (15,000 pounds) of lift,” Egal told ABC.
“That’s not the best, but we got the engineering down to it, so we’re pretty happy with it.”
Egal said the design changes made the 777 even more aerobatic, making it more efficient and capable.
It also made the plane more maneuverable.
The new 777X will be tested for the first time later this year.
Egan expects the plane to fly by 2020.
Egan’s team also plans to build another 777X, which he said will be able “go to Mach 3 and be much more aeroblitzed.”
Egon told The Associated Press that the new 777 is still being designed, but that the design team has found a way of adding some more power to the engine.
“That engine has a little bit more throttle, and that’s been the biggest change,” he said.
“So, that’s why we’re going to make a smaller engine and try to get a little more power out of that.
We want to make the engine smaller so it can be used more in the aerobatics department.”
Eggert, of Jet Propulsion Laboratory, said Aerojet is looking to continue to improve the engines for future aircraft.
“With the 777 we’re trying to make some big changes,” he told ABCNEWS.
“We want to do a big engine upgrade, but to do it at a lower cost and with a shorter life cycle.”
