This week brought together representatives of Europe's aerospace industry, the research project Dream, to discuss the future of aircraft engines to become more eco-friendly. One of the questions is how to reduce noise and fuel consumption of aircraft engines to protect the environment. The project involving a total of 44 aviation industries, universities and research institutes in Europe and will run for three years. Dream started in February and has a budget of 40 million. Bland deltagarna märks tunga företag som Airbus, Rolls-Royce, Snecma och MTU. Among the participants felt heavy companies Airbus, Rolls-Royce, Snecma and MTU.

During this week, over 30 representatives of Europe's aviation industry will meet in Trollhättan. The aim is to discuss the future of aircraft engines to become more environmentally friendly. Volvo Aero is host for the visit and the meeting takes place on the Production Technical Center in Innovatum in Trollhättan. Participants are a number of the actors involved in the research project DREAM (Validation of Radical Engine Architecture), which started in February this year. The project fits the development and testing of engines in order to reduce aviation emissions and environmental impact. At Volvo Aero will test concepts to reduce noise and fuel consumption.

Quieter planes with lower emissions are set for take-off VISITORS to the Farnborough air show are used to loud noise, but this was different. A high-pitched buzz throbbed across the Hampshire airfield, prompting spectators to put down their Pimms and crane their necks at the aircraft soaring above them. It looked like an ordinary commercial airliner – but there was something odd about its engines. One was conventional, while the other had two rows of curved propellers protruding hedgehog-like from the rear. This was the source of the unnerving howl. The unducted fan, as the banshee powerplant was called, flew at Farnborough 21 years ago.

Results of wind tunnel open-rotor blade testing that started in Russia earlier this month for the European project DREAM (valiDation of Radical Engine Architecture systeMs) will be available by the end of the year. At Russia's Central Aerohydrodynamic Institute one fifth- and one seventh-scale blade testing is being carried out on existing electrically powered rigs at speeds of up to Mach 0.85. Started a year ago, DREAM is a three-year €40 million ($56.5 million) project led by Rolls-Royce to investigate open-rotor engines and new fuels. A baseline open-rotor engine design is now being validated until November after "brain storming" in March led to concept study work beginning in May.
