2 Clean Sky = JTI JTI = Joint Technology Initiative Ny typ av EU-program
Public/private partnership (JU, Joint Undertaking) 7 år, Budget 1600 M€ Stöttas av det svenska FLUD-programmet Clean Sky är en av flera JTIer Clean Sky tar fram demonstratorer inom sex teknikområden Ett av dessa är motorer (Sustainable and Green Engines, SAGE) SAGE leds av Rolls-Royce och Snecma SAGE budget 425 M€ Volvo Aero är Associate member => Identifierade som nyckelspelare för att projektet ska lyckas Ansvarar för större arbetspaket 21 M€ budget October 2010 Clean Sky

3 ”Innovationsupphandling” från EU
Det övergripande målet med Clean Sky är att ta fram teknologi som tar oss snabbare till ACAREs mål för år 2020: -50 % CO2 Halverat buller -80 % NOx October 2010 Clean Sky

Volvo Aero focus on design, development and manufacturing of complex lightweight static and rotating structures. Advanced manufacturing and manufacturing process simulation technologies developed in FP5 and FP6 projects are a key to success.

17 “Make It Light” för att minska CO 2
day month year “Make It Light” för att minska CO 2 Volvo Aeros mål är att minska vikten på kalla och varma strukturer med 20%, vilket kommer att minska vikten på framtida motorer med nästan 3%. Det sparar kg i bränsle för ett normalstort passagerarflygplan. Om denna teknik användes i den nuvarande globala civila flygplansflottan, skulle CO2-utsläppen minska med 1,3 miljoner ton om året. Som jämförelse släppte flygtrafiken i Sverige ut 1,5 miljoner ton CO2 under 2005. The 20% reduction is Volvo Aero´s adopted technology target for hot and cold structures. From a recently designed engine the weight of the intermediate case, fan OGV and turbine exhaust case was estimated at 13.4% of the engine weight. 20% of this gives a 2.68 % saving on engine weight. For a next generation single aisle aircraft the engine weight was estimated at 2300 kg. This in turn gives a 61 kg saving per engine. By rescaling the aircraft for constant mission range and payload the aircraft mass decreases a total of 262 kg. This aircraft saves % fuel compared to that with the baseline engines. The baseline aircraft uses 1720 kg fuel per average mission hour. For 4000 hours utilization this gives a baseline consumption of 6860 tons per year from which kg can be saved. The global commercial fleet (IATA) was estimated to use 161 Mtons of fuel 2006, which generated 507 Mtons of CO2. The potential improvement of 0.255% was applied to this quantity. SIKA (Statens institut för kommunikationsanalys) reports in "Civil aviation 2005" (SIKA 2006:17) that "Emissions in engine exhaust gases from air traffic in Sweden" contained thousand tonnes CO2.
