“DREAM” – validation of Radical Engine Architecture systems – is a Framework Programme 7 Call 2 project with a total budget of EUR 40 million and which is in its fourth and final year in 2011. This project comprised of 44 partners from 13 countries from the EU, Switzerland, Russia and Turkey and comprised of larger Original Equipment Manufacturers (OEMs), SMEs, universities and research establishments. It is the response to commercial and environmental pressures that have come about mainly as a result of two main factors: the continued pressure to reduce CO2 and the future availability and cost of Jet A1 fuel. “DREAM” has studied designs for contra-rotating open rotors and has been developing novel systems to achieve, versus Year 2000 reference engines: (i) a reduction in CO2 by 27% (7% better than ACARE goals); (ii) a reduction in noise by 9 dB cumulative.
