Right from the start I need to point out that this article is date September 2009.

I don't recall seeing it linked anywhere, but it includes some interesting information on the Trent 900 upgrade programme.

http://www.aviationweek.com/aw/gener...?channel=mro&id=news/rolls9289.xml

Quote:
"We're committed to a 1% fuel burn improvement. We're taking technology from the Trent 1000 and 700EP and putting that into the Trent 900. That technology wasn't available for the Trent 900 at certification but is part of a package we've launched," says Ian Crawford, Rolls-Royce's head of Airbus programs.
Quote:
The core of the package will be the introduction of elliptical leading-edge modifications throughout the entire compression system, including improved high- and intermediate-pressure (HP/IP) compressor blades and vanes.
Quote:
As with the Trent 700EP, the 900EP enhancement will be offered as an upgrade kit for existing engines. "The modifications are all optional and are completely interchangeable. You will get the full 1% if you install all the parts," says Richard Keen, Airbus programs marketing director. "From 2011 this will be the production standard for all new Trent 900 orders," he adds.
Quote:
"We're already having thoughts on what comes after this," says Crawford. "We are looking at the Trent 1000 and Trent XWB [for what] might flow back into the Trent 900.
Quote:
Although he is not specific about what XWB features could find their way into Phase 2, the anticipated benefit is expected to exceed the fuel burn reductions in Phase 1. "The prudent thing is to run the XWB and get the empirical data," he says. "We're not yet committed to Phase 2 as that represents quite a big change to the engine. [That program] is probably 18 months to two years away after 2011."

In a nutshell the plan is 1% improvement as the 2011 standard (retrofittable), and greater than 1% more c. 2013..
Another couple of hundred nautical miles for 2013 A380's.
Won't hurt I guess  

Enjoy

RR won the crucial launch order from SQ and followed this with significant wins at LH, QF and others. They still have more customers than EA do.

But EA snagged the very considerable prize of EK and they have now pulled ahead of RR in unit sales.

Recently - and tellingly, I suspect - EY chose EA.

My impression is that the GP7200 is currently performing a tad better than the T900 is.

It will be fascinating to see which way future customers go.

QR have still not selected an engine. My guess is that they'll announce one at Farnborough next month along with a repeat order for A380s. Everyone seems to assume they'll go for EA. But I wonder. I recall confident predictions that LH would choose EA and EK would choose RR.

Then there is the rumoured Asiana order and the LoI from Vietnam Airlines.

Qatar, Asiana and Vietnam are all customers for the A350 and, therefore, the Trent XWB. Might that be a factor? (Didn't seem to be for EY...)

In truth, the A380 engine competition still seems pretty even. We'll need to see several more orders before it's clear who has the edge.

Airbus's range payload charts appear to support this from a fuel burn standpoint although closely enough that it may not be the whole of the economic picture.

Either way, the improvements stated for 2013 should mean about an extra 200Nm for Trent powered A380's.
Add the 100Nm of the 4t MTOW increase and it seems to confirm that we should see 2013 A380's with 8 500Nm nominal range capability.
There's the 4t OEW reduction programme to be factored somewhere as well of course.

It's interesting to note that the public statements from both engine OEM's committing to staying ahead on the A380 seem to contradict those who dismiss the A380's sales potential. They both seem prepared to spend a fair bit of money keeping their respective offerings at the front  

There's perhaps an interesting side question there for the A350 in the long term....

The TXWB newsletter 9/09 said the 1% would be availible for deliveries from 2012, which I believe is when the first BA and the follow up SQ order begin to be delivered.
