GE Engine Orders From Korean Air

Thu Nov 23, 2006 2:15 am

Fair use excerpt

http://biz.yahoo.com/bizj/061122/1380206.html?.v=2

Five 777-200 freighter aircraft, powered by GE90-94B engines, valued at $200 million;


This says GE90-94B instead of the GE90-110's of the LR. Is this an error, or is there a fuel economy/increased payload (lighter engine?) reason for this?

It must be an error. The 777-200F is based on the -200LR, so it should have the GE90-110B or the -115B.

Agreed. Perhaps KE's current 772ERs use the GE90-94B and that is what the writer found when they did some research?

Know we know why GE is reluctant to participate in the A350-X engine program. As sole supplier on the 773ER& -200LR, why upset the money cart  dollarsign

I don't think so. AFAIK, KE is one of the biggest operators of PW4000 powered 777s, along with UA and maybe OZ.

Quoting Justloveplanes (Thread starter):
Is this an error

Has to be an error. You need 110k or even 115k to get good payload out of the 777F. The 777F is only certified for the 124" diameter version of the GE-90, not the 118" diameter version. I don't know if its available as a 94k derate... that doesn't make sense to me...  scratchchin  Widebodyphotog, do you know if a 94k is available? What does it do to the 777F's operation envelope?

The GE90-110B/115B are the only engine options for the 772LR or the 777F.

That has to be a mistake. First off, there isn't much reason why you'd want a 94 over a 110 or 115, in terms of performance or economics. No one has even really ordered their 772LR will the 110 even, they all seem to go for 115. Plus, I doubt Boeing would go through the trouble of putting and certifying the smaller diameter GE90 on the 772F. It's possible, however pointless, to software de-rate a GE90-110 down to 94,000lb thrust, but it would, I'm sure, have a different model designation than the smaller fan 94k thrust GE90...

It has to be a mistake.

Not that it matters much...buy a -110, operate it for several months, flash the engine computer, and voila, instant -115. Same deal with SQ's 777-200ER operated at lower MTOW.

Small correction, I believe the -110B1/ 115B fan diameter is 128", whilst the -94B and the rest are 123".

Surely this is just a typo by the journalist(s)

It's a blatant error, KE has selected the GE90-115B1L to power their ships as all other operators have so far...

Exactly, no other fan diameters for GE90 exist.

Actually, the B-777F isn't certified for anything right now. It is only being offered by Boeing.
