Latest E3E Engine Core Test Produced "Excellent Results"
Rolls-Royce says it has successfully run the latest core engine
build in its E3E (efficiency, environment, economy) two-shaft
research program. E3E is developing technologies which increase
engine temperature, pressure ratio and component efficiencies,
together with a 25 per cent-plus increase in thrust to weight
ratios.

These technologies are designed to reduce fuel burn and CO2
emissions by 15 per cent, compared to similar engines currently in
service. E3E lean-burn will also reduce NOx emissions as part of
the company's drive to meet ACARE (Advisory Council for Aeronautics
Research in Europe) targets of a 60 per cent reduction by 2020.
The program is designed to address future customer needs in the
corporate and narrowbody sectors.
The latest Core, 3/2b, has produced excellent results during 40
hours of running at Stuttgart University altitude test facility,
far exceeding flight envelope requirements. Mark King, Rolls-Royce
President - Civil Aerospace, said: "Our E3E technology, which is at
the heart of our future two-shaft engine product strategy,
continues to make great progress."

Rolls-Royce started design of the engine in 2003 and continues
to run intensive HPC, combustor and high pressure turbine rig
programs to support the Core 3/2b demonstrator. Further builds of
Core 3/2 will be tested in 2011 and 2012 and will include 1,200
cycles of endurance testing representative of maximum take-off
conditions. E3E is part of the German Aeronautics Research Program,
funded by the Ministry of Economics and the Federal State of
Brandenburg.
