Skip to comments.The Biggest Jet Engines in History Are Finally Ready to Power Boeing's Biggest Plane
Posted on 01/07/2019 8:12:07 AM PST by C19fan
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.

That’s a big goose net. Probably suck up the whole gaggle in one swoop.
Sometimes bigger aint necessarily better
Yeah, that was poorly written.

I see the doom and gloomers are out in force this morning.
I read this at Wiki...
Customers bemoan the loss of engine competition, like Air Lease Corporation's CEO Steven Udvar-Hazy who wants a choice of engines. Airbus points out that handling more than one engine type adds millions of dollars to an airliner cost. Pratt and Whitney said "Engines are no longer commodities...the optimization of the engine and the aircraft becomes more relevant."
"SEE!? SEE?!? We don't need those nasty Fossil Fuels!! GE stands for General ELECTRIC!!"

IMAGINE THE CARBON FOOTPRINT!!!!!..................
Replace ‘moonbat’ with AOC...................
I’m not convinced that 2x “giant” engines (even if the B-52 could fly on only one engine after getting hit by a missile or AA flak), but it is an interesting question.
The B52 has 8x small, relatively inefficient old medium bypass engines on 4x struts now. Each small engine does tend to self-shield its partner (Vietnam flak and AA missile rarely took out both engines in a pod when they were hit). But, do 8x low-bypass or 4x high-bypass engines provide more of a “target area” for debris and frag particles than 2x larger diameter engines, one on each side?
Reading the stories of each B52 shot by North Vietnamese SAM’s doesn’t seem to prove the theory either way.
My instinct says “Better 2x engines on each wing than 1x engine, since the out-of-symmetry forces and damaged ailerons and tails and flaps would make controlled flight harder after the rocket hits.”

They probably will be able to capture , gut and prepare the gooses and serve a planeful of passengers for dinner on the flight.
Longer than a soccer field and able to leap tall buil....... Never mind
Yeah, ask Rolls Royce about that.
