Obiettivo
Since the publication of the ACARE goals, the commercial and political pressure to reduce CO2 has increased considerably. DREAM is the response of the aero-engine community to this pressure. The first major DREAM objective is to design, integrate and validate new engine concepts based on open rotor contra-rotating architectures to reduce fuel consumption and CO2 emissions 7% beyond the ACARE 2020 objectives. Open rotors are noisier than equivalent high bypass ratio turbofan engines, therefore it is necessary to provide solutions that will meet noise ICAO certification standards. The second major DREAM objective is a 3dB noise emission reduction per operation point for the engine alone compared to the Year 2000 engine reference. These breakthroughs will be achieved by designing and rig testing: – Innovative engine concepts – a geared and a direct drive contra-rotating open rotor (unducted propulsion system) – Enabling architectures with novel active and passive engine systems to reduce vibrations These technologies will support the development of future open rotor engines but also more traditional ducted turbofan engines. DREAM will also develop specifications for alternative fuels for aero-engines and then characterise, assess and test several potential fuels. This will be followed by a demonstration that the selected fuels can be used in aero-engines. The DREAM technologies will then be integrated and the engine concepts together with alternative fuels usage assessed through an enhanced version of the TERA tool developed in VITAL and NEWAC. DREAM is led by Rolls-Royce and is made of 47 partners from 13 countries, providing the best expertise and capability from the EU aeronautics industry and Russia. DREAM will mature technologies that offer the potential to go beyond the ACARE objectives for SFC, achieving a TRL of 4-5. These technologies are candidates to be brought to a higher TRL level within the scope of the CLEAN SKY JTI.
