Boeing is set to debut its biggest plane ever next month, and the 777X has finally been paired with the gargantuan GE9X engine that will propel its flight.
The plane is currently housed in Boeing's Everett, Washington, assembly plant, where pictures show it looming over workers as they prepare it for its maiden flight.
The GE9X engine is the biggest turbine engine in the world. At roughly the size of an entire Boeing 737's fuselage, it was subjected to test flights last March when a single turbine was hitched to a 747 testbed.
The engine includes a composite fan more than 11 feet in diameter, tucked into a 14-and-a-half-foot engine capsule, or nacelle. It has 16 composite fan blades and hangs on the 777X's 118-foot wings, which make the new planes the largest two-engine jets in the world.

I hope we make thousands of them.
That’s geese...a great source of grease!
Depends on which girl your asking
For pure fuel efficiency in airliner use, two large engines always perform better than four smaller engines.
The Airbus A330 and A340 are basically identical aircraft except for the engines. The A330 has two, and the A340 has four.
The A330 is much more fuel efficient, and the A340 has all but died out as a result. It's only reason for being was for long range over water routes where 3 or more engines were mandatory for flight safety.
But then the ETOPS rules (Extended-range Twin-engine Operational Performance Standards, a.k.a Engines Turn or Passengers Swim,) allowed twin entine aircraft to fly these routes, killing off the A340.
As for the B-52, there has been talk for literally decades about re-engining the B-52 with either four or eight high-bypass turbofans. The latest thinking is eight small high-bypass turbofans from the Gulfstream 650 would be easier to certify than four larger turbofans under the wings.
I recall seeing a similar pic 45 years ago when Boeing was testing the 747’s P&W JT9D on a B 52.
Holy Mama that’s Huge!
2 engine a/c lots less maintenance costs.

AOC for moonbat queen!!
All good points. And we all know that the B52 only "needs" fewer engines because of A) the global warming hoax and B) some contractor wants to build them. Someone I knew who'd been a flightline mechanic for the B52 said the engines are "pigs", a real mess after a flight. The have one job though, which is to get the job done, and they've done that over a number of iterations since they first took flight in the early '50s.
bleeech
Thanks.
I didn’t even have to ask.
FReepers rock.

An engine with restrooms...Wow! Neat-O!
That thing will eat a few inattentive ramp rats.
