The Biggest Jet Engines in History Are Finally Ready to Power Boeing's Biggest Plane
 

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.

I think we might have known that already. :O

Boeing is reportedly planning to roll it out in the next month or two, which I suspect many don't know.

Yeah but the PICTURE impressed me. :)

Ahhh yes, the folding wingtip version :eek:

I don't care what the brochure says, that alone will keep me off the jet. At least the 787 gets there, even if it is with a numbum.

Better stay off those with retractable landing gear and moveable flaps too. You know what deathtraps those have proven to be.

I think there's a fairly crucial distinction between bits that are intended to move in flight and those that aren't meant to. :O

but these are "meant to be"

Yes, but the comparison was between those and folding wingtips, that aren't.

Do try to keep up. :O

It's a lot easier to keep things from moving in flight that aren't supposed to move, than to keep things moving in flight from moving when they're not supposed (or moving contrary to how they're supposed to)

The SLUF and 'toom flew with wings folded.
The Tomcat could fly with asymmetric sweep.
So even in the event of pilot error, or some type of mechanical failure, surely there's no in flight worries about the new triple 7's last three metres on each side?
I'd be more concerned about the person sitting in Seat 0A forgetting to fold `em coming into the gate, and trading paint with someone or something else.
And no doubt there'd be all sorts of alarms and things to stop that happening...

C'mon, the USN was flying fighters with folding wings off carriers in WW2. I think they've probably worked out the kinks by now! :)

Folding wings? That's just some sort of crazy science fiction.

Don't get too close though... :sad:

hope so, it helps to know which way the loads are on the pylon when something breaks

Nice cap...

Ouch!! :) :)

tandem wing
 

The folding wingtip thing makes me wonder: will we at some point see large aircraft with tandem wings?

What would be the disadvantages with a forward mounted tandem wing instead of extending the wingspan?

More structural parts needed to mount the wings, more drag, forward wing possibly interfering with airflow to engines at certain AoA, what else...? Any advantages that could make it happen?

EEngr. Great picture. What a magnificent machine. I've never seen that photo before. You got any more?
