Talk:General Electric GE90

From Wikipedia, the free encyclopedia

What kind of speed can it generate, that is, at what speeds can it propel an airplane (in this case, the 777)? That kind of information is interesting to have in an article such as this one, since laymans, such as myself, can't really relate to the figure for how much thrust the engine can muster. This needs to be "translated" into something more familiar to the average user — which makes the article more interesting for the casual reader. Regards, Redux 16:01, 10 March 2006 (UTC)

[edit] Transport to Boeing

How is this engine transported to the Boeing production site in Everett ? In parts without the fan in a 747 freighter ? Or completely assembled and simply fixed at the wing of a two-engine 747 ? 217.86.42.111 07:52, 17 June 2006 (UTC)

Transport answer:

The engines undergo final assembly (mating the fan and core assemblies) and testing in GE's facilities in Ohio. They are then trucked overland to Boeing Seattle where the EBU hardware is installed (aircraft interface equipiment). They are then further trucked up to the Everett factory for installation on the aircraft. Further ground runs are conducted on the aircraft before first flight and delivery.


What kind of tolerances?

[edit] Guinness Book of Records

The sentence "[...] The latest variant, the GE90-115B, has a fan diameter of 128in and holds the Guinness Book of Records for the highest thrust [...]". In its currrent version the sentence reads as if the engine was capable to hold a copy of the Guinness Book of Records. I advise to correct this. --Wendelin 10:33, 24 October 2006 (UTC)

I agree and have reworded accordingly --JCG33 21:41, 30 December 2006 (UTC)

[edit] B747 ETOPS?

Is it possible to re-engine a B747 to 2 x GE90115B configuration? This would save a lot of fuel due to less drag and less labour for engine maintenance, with more thrust. You would probably need to add one truss per wing, which would couple the original inward and outward engine pylons so they can share the load and stress bearing and fix the new engine to that. Would the new engine fit ground clearance? Is this being done to the A380 adversary B747 Next? 193.226.227.153 20:20, 24 February 2007 (UTC)

[edit] A380?

This engine with its high thrust would seem to be a match made in heaven for the "super jumbo" looking at the RR trent article it seems it produces far less thrust, and has been chosen by most of the early customers of the A380. Thoughs? Golden Dragoon 06:37, 25 February 2007 (UTC)

The GP7000 on the A380 is directly derived from the GE90. —Joseph/N328KF (Talk) 15:44, 25 February 2007 (UTC)
yes but the GP7000 is said to be rated at 81,500lbs of thrust compared to the figure in this article saying the GE90 is rated at at 115,300lbs with a peak (in the guinness book of records) of 127,900lbs.

I may be missing something but the higher thrust GE90 would seem to be a more logical choice than the Trent or GP7000. Golden Dragoon 10:00, 1 March 2007 (UTC)
