RR Launch Trent 700EP

"Rolls-Royce announced today that Etihad Airways, the Abu Dhabi-based national airline of the United Arab Emirates, has chosen the Trent 700EP to power a further eight Airbus A330 aircraft. The Trent 700EP is the latest and more fuel-efficient version of the best-selling engine for the A330."

Actually, these are old orders (for the A330) and they have been designated -x43s (ie.e. RR) on production lists for some time. So no great news there.

But, if I'm not wrong, this is the first public reference to something called the Trent 700EP.

EP = "enhanced performance" or "eats Pratt" or what?

RR have been tweaking the Trent 700 for some time. So is this just further incremental upgrades or something more?

The 0.3% fuel burn advantage for new build engines over the retrofit is interesting. I wonder what the difference is.

Were these the T700 figures used by Astuteman in his recent estimates of new build 332 performance, or is this a little more? Looks as if the predictions of the "old" engines being improved rather than replaced by newer models will be the RR path. However the gap between the 700EP and an EPised 700 is fascinating.

Endangering Pratt ?

I was reading now the RR homepage front to back but only abbrevations with the Trent 700 used are
> LP
> IP
> HP


Quote:
The Trent 700 is a three shaft high bypass ratio engine powering all variants of the A330. It has a Low pressure system (LP), an Intermediate Pressure (IP) system and a High Power system (HP)

No mention of "EP" anywhere except in this press release....

I presume this is technology from the T900 and T1000 filtering down, thus keeping RR ahead on the A330 AND closing the gap between it and the 787.

The Trent 1000 for the A330 would turn more heads IMO or the GENX. Question is if it would only hurt the 787 or A350XWB too..

Nope. The SQ A330s will be the first aircraft with the T700EP, the engine already exists, and is already hanging off the wing of an A330 in TLS.

I don't think this is at all uncommon. We've seen GE90 see almost constant changes and improvements, likewise with PW4000 also. It's good to see RR not resting on its laurels with the A330 family and improving an already strong engine.

As for closing the gap with 787, I think it's going to take something a little more than .3% fuel burn improvement to do that.

True.
And I don't think anyone expects the T700 to match the T1000 or GEnx anytime.

As a slight correction, the improvement over current in-service engines is, according to the article, 1.3%, not 0.3%

As I understand it, there is a further batch of improvements due late 2009/early 2010, if memory serves.

When added to the 5 tonne increase in MTOW, they should make the A330 continue to be a strong performer, despite the (narrowing) SFC disadvantage relative to the 787.

Something similar happened with the Tech Insertion package on the CFM56-7...the newbuild has slightly better performance than the retrofit. I think it's something to do with some parts that are integral to the engine case (maybe seals?) that you can't retrofit.

Or should I cry? 1.3% is HUGE! That is 70nm+ free range.

This does not close the gap with the 787 by any means. However... due to the lengthy delay until 787 deliveries, this keeps the A330 in production for a while. It will also make A330F's more attractive.

Sigh... Pratt... why didn't you listen to your engineers on the PW4173? Sigh...

Quoting Baroque (Reply 2):

Its probably a subtle difference in engine contour that cannot have all of the parts retroffited without buying a new engine. Its not worth replacing an engine for 0.3%...

SQ will actually be the first operator of the Trent 700 EP. In the Dec 8th AWST there is an article about the EP, also Pratts PW4000 Advantage 70 with 2% higher thrust and 1% better fuel consumption, increased durability and reduced mx costs. Kingfisher, TAM, Flyington first customers. GE is offering the Tech CF6 with HP turbine upgrades, better blade cooling, lower mx costs and improved fuel burn retention. Finnair first customer.

I have been surprised how little attention the EP has gathered, especially as 330 customers seem to be buying 700EPs hand over fist, so some people must know about it!  bigthumbsup

Is the 330-200 in some senses the 787-7 that airbus has chosen not to compete against with their (larger) 350 range? Some have stated on this forum that over short to medium ranges the 330-200 offers very close performance figures to the yet to fly 787-7.

Just wondering here.Since the "core" output of the Trent 700 is very similar to the trent 1000 would it be possible to re-fan the -700 with the -1000 fan and casing.The developments over the last few years with third gen "scimitar" blade technology have been great.

If it were possible it may give Boeing a bit of a fright I warrent.

Did you mean 787-8?
The A330-200 and 787-8 are so near in physical size, weight, and capacity, it's extraordinary.
And, for now at least, the A330-200 seems to be capable of holding its own in the marketplace.

Once upon a time I thought Airbus were going to have a gap in their portfolio at 250 seats, at which size the 787-8 would be completely unopposed.
Just goes to show why some CEO's are "real", as opposed to "armchair"  thumbsup
