Trent 1000 versus GE9X engine reliability

[bill nye scienceguy!]

what's the consensus?

They are both turbine enines to be used on the 787. If you want more than that, you need to seriously write more than 3 words.

I'll go one step further...three vs. two spool. NEXT!

 

[bill nye scienceguy!]

ok. In the view of PhysicsForums, which is mechanically the better engine, is Rolls Royce or GE better placed to support the 787 (if it ever gets delivered, which is another question entirely) and in the long-game, will two or three spool win the rotatives war?
