Rolls-Royce completes testing of latest E3E engine core

Rolls-Royce successfully completed testing of the latest build of its new two-shaft engine core, known as Core 3/2d. The tests, which are part of the E3E (efficiency, environment, economy) research programme, were carried out in the altitude test facility at Stuttgart University. Tests included operation of a lean burn combustion system in simulated bad weather during which Core 3/2d operated safely and successfully performed windmill re-lights in conditions equivalent to a tropical hailstorm. Emission and performance measurements and functional tests were also carried out. Dr Karsten Mühlenfeld, Rolls-Royce, Director Corporate and Engineering, Germany said: “These 40 hours of testing are another step forward in our continued work to develop environmentally friendly technologies. These technologies will enable future Rolls-Royce engines to contribute significantly to the goal of the Advisory Council for Aeronautics Research in Europe (ACARE) of reducing nitrogen oxide emissions by 80% by 2020.”
