Within the E3E framework of the German Aeronautics Research Program Rolls-Royce Deutschland developed key technologies for an all new core engine that incorporates major advances with regard to environmental friendliness, efficiency and economy. The derived E3E core engine will serve as a scalable baseline for the future two-shaft engine family in the medium take-off thrust range. The latest build of the core engine demonstrator has accomplished a 40 hours test campaign in 2010 aiming at functional testing up to the master design point as well as intensive altitude experiments. The core engine features a nine stage HP compressor with an innovative axial load compensation system to cope with the high pressure ratio of 22:1 in one spool. A staged lean burn combustor demonstrates altitude relight, quick windmill relights and cold start capability. The 2-stage shroudless HP turbine is designed for strong rubs into the ceramic liner material to retain high turbine efficiency. The results and analysis will be presented in this paper.
