Rolls-Royce completes latest E3E testing

Oct. 12, 2011, Las Vegas, Nv. - Rolls-Royce, the global power systems company, has made significant progress in its E3E (efficiency, environment, economy) research programme, having completed testing of the company’s latest two-shaft engine core, known as Core 3/2c.

Technology developed as part of the E3E programme forms the basis of the Rolls-Royce Advance2 – future two-shaft engine programme.  Testing of the Core 3/2c was dedicated to further improving the performance of the high-pressure turbine and emissions.
E3E technologies are designed to reduce fuel-burn by 15 per cent, compared to similar engines currently in service and achieve emission levels, which are up to 45 per cent lower than CAEP6 regulations.
The Advisory Council for Aeronautics Research in Europe (ACARE) has set a target of reducing nitrogen oxide emissions by 80 per cent until 2020.  E3E technology will make a significant contribution towards meeting these targets.
Dr. Holger Klinger, Rolls-Royce, Chief Project Engineer, Technology Programmes, said: “Completion of these important tests marks another significant step forward, demonstrating excellent progress in integrating new technologies which will allow future engines to meet and surpass ACARE targets.”
The Core 3/2c produced excellent results during 32 hours of running at Stuttgart University altitude test facility. Further development of the Core 3/2 will include testing an advanced lean burn combustor module; testing is scheduled for 2012.
