A346, Why Only Trents?

Sun Sep 15, 2002 5:30 pm

I know that almost all airplans are available with GE, PW and RR engines.
Why the 346 is available only with RR engines?

This can be a problem because the most of Europeans carriers (except BA of course) prefer GE engines.

I know that the 380 will be available with RR and a joint venture between GE and PW.

Which are the main differences between GE, PW and RR engines?

Rolls Royce was the only engine maker who had an engine (Trent 500)available for the new A340-500/600 models. Hopefully P&W may soon offer a PW4000 series engine for these aircraft where we might see NW order them.

Simply put - engine makers will sometimes not develop an engine for a new aircraft unless granted exclusivity. This is especially true if the market is thought to be to small for two players.

Also, an exclusivity grant is one way airframe makers can entice engine makers into becoming risk sharing partners in an aircraft program. They contribute some money towards airframe R&D and in return they get a share of the profits and/or an exclusive deal to supply the engines.

This has happened with both the new 777 versions and the new A-340's.

Are there any time limits on the new exclusivity deals? I would think there would be...

What if Boeing put pressure on GE and P & W to not design an engine for the A340-600 so airlines wouldn't buy it because of it having only one engine option, and therefore giving the airline no other choice but to buy the 777, if they wanted engine options.

DC10Tony, are you forgetting that the GE90 is the exclusive engine for the new 777-200LR & 300ER models? If Airbus offers a PW4000 series engine on the A340-500/600 models as an option including the RR Trent 500, it would lure customers away from the new 777-200LR & 300ER who don't want the GE90.

I think the reason why the GE90 is the exclusive engine for the 777 models you're talking about is because of the engine's power. It's the most of any other 777 engine offering, and that's needed to power an aircraft which is marginally smaller than the 747 and only using 2 engines.

That's just my theory.

Why only CFM on A343, A342?

Hello Lewis, regarding the CFM56-5C on the A340-200/300, we could have had a SuperFan version of the IAE V2500 as an option, but because of technical risks IAE dropped the project leaving the CFM56-5C as the sole powerplant.

I think the reason only the 772LR+773ER have GE engines is because GE was a risk-sharing partner with Boeing when the 777 was launched and GE exclusivity above certain model weights of the 777(which kick in around 772ER-LR I guess)was part of the deal.May be wrong though

Having the GE90 as the sole powerplant on the 777-200LR & 300ER models might turn away customers who have engine commonality with P&W or RR powered aircraft in their fleets. If Airbus offers a PW4000 series powerplant on their A340-500/600 models might give them the advantage they need in getting orders from P&W as well as RR customers.

Flight International stated that GE is paying almost half the certification costs of the new B777s in return for exclusive engine rights. RR was developing a higher thrust engine, which had already run at over 105,000lb, in anticipation of B777 growth models. PW on the other hand admitted its PW4000 engines on the B777 had reached their limits.
