The crux of the Rolls-Royce release is the following information. (I underlined what I felt important)
"Rolls-Royce ... is looking to build on the success of the Trent family of engines with two new generation engine designs.
The first design, Advance, will offer at least 20 per cent better fuel burn and CO2 emissions than the first generation of Trent engine and could be ready from the end of this decade.
The second, UltraFan™, a geared design with a variable pitch fan system, is based on technology that could be ready for service from 2025 and will offer at least 25 per cent improvement in fuel burn and emissions against the same baseline."
Additional details are provided :
"The designs will feature architecture and technology improvements, all currently at an advanced stage of development, that include:
• A new engine core architecture - to deliver maximum fuel burn efficiency, low emissions.
• A CTi Fan System - carbon/titanium fan blades and a composite casing that reduce weight by up to 1,500lb per aircraft, the equivalent of carrying seven more passengers at no cost.
• Advanced ceramic matrix composites - heat resistant components that operate more effectively in high turbine temperatures.
• A geared design, called UltraFan™, which will deliver efficient power for high-thrust, high-bypass ratio engines of the future."
To me, the striking points are :
- Carbon/titanium fan blades and a composite casing could be available from 2020 on ; - Rolls-Royce invests in research on a geared engine.
I wonder, though, what a 20%/25% improvement over "the first generation of Trent engine" means when translated into a comparison with RR's latest products (TXWB)

The Trent 700 is the first in the Trent series. So I think the baseline they're referring to are those engines on the first batch of A330s. But 20-25% improvement is a big jump anyways.

A very interesting new article by Aviationweek on the RR Advance and the Ultrafan. Rolls-Royce Details Advance And UltraFan Test PlanI'm very excited about the development of these new engines and the potential for use on future aircraft: A350 derivatives? A380neo? One of the most interesting bits I find in the article is this: This is big, IMO. You can have good manufacturing and maintenance savings despite having two separate engines spanning from 40k to over 100k thrust to power your next-gen narrowbody replacements and widebodies.

It has been an exciting past couple of months in aviation. Let's add this to the list. Rolls Royce test flew the Advanced Low Pressure System (ALPS) featuring the Carbon-Titanium fan for the first time a few days ago using a modified Trent 1000. I hope they keep the blue for commercial versions.

United Tech CEO says widebody engine unlikely anytime soonGood to note, however, that they can actually do it now, but it's just the lack of a sound business case given that there are no major new/re-engine widebody programmes in the near term aside from the A380neo possibility. I also find the comment on after-market support, maintenance and overhaul of narrowbody engines being more lucrative very interesting. It makes sense as he says widebody engines are put under less stress compared to the narrowbody engines due to the lower number of cycles.

Most important are of course the pure numbers. How many NB are there around and how many WB. It is close to one order more....
