Next generation of GEs mega engine was tested this week. I remember seeing them test the GE90 in Mojave back in the mid 1990s.
For reference the other engines on the 747 have fan diameter of about 8 feet.





You get what you pay for...
So keep in mind how much you paid for this advice.

At 0:23 you can see which engine is the one being tested.

Reminds me of, 'What's Wrong with this Picture?" puzzles.

Too bad the 47 couldnt be fitted with 2 of these to make them more efficient and keep them in skies.

Those fan blades - works of art.
Actually the whole engine is drool worthy.

Seriously?

You can buy a new 747-8 with General Electric GEnx engines, or Rolls-Royce Trent engines.

The biggest problem is seat capacity per fuel burned -
The A380 is a bit bigger (50 more seats) with about the sane fuel burn,
and the newest 777 will be almost as many seats, but far less fuel burn.

The 747 was A M A Z I N G to the airline industry when introduced -
and forever changed air travel.
It will be 50 YEARS OLD next year - impressive by any standard.
It's just that it's time has come...........
and better options are nor available

The 800i uses GEnx like dreamers do

I have been on many 380s many are never full unless they are heavily discounted one subsidized airline kept them in business
I dont like hubs of the airlines choosing and blame an arrogant ME company for spreading that nonsense

GE on the nacelles and Boeing on the fuselage. None others need apply.

Does the engine on a twin act like an air brake when shutting down in flight?

ALL naircraft engines create drag when not producing power.

ETOPS = Extended Twin Engine Operations (aircraft have to be certified to do this) allows over water flight if one engine fails.

Thats been a big winner for many airlines and passengers along with an exceptional safety record

Depends.

In most cases, no. But a seized engine will create more drag than one that still rotates. Depending on the speed of the airplane at shutdown, the thrust on the other engine, and the altitude at which it happens, you may get a lot of yaw, or just a little...
