Clean Sky

Clean Sky 1
Clean Sky, a Public Private Partnership between the European Commission and the Aeronautical Industry, was set up to bring significant step changes regarding the environmental impact of aviation.

Clean Sky will speed up technological breakthrough developments and shorten the time to market for new and cleaner solutions tested on full scale demonstrators, thus contributing significantly to reducing the environmental footprint of aviation (i.e. emissions and noise reduction but also green life cycle) for our future generations.

The Clean Sky JTI is one of the largest European research programmes ever, with a budget estimated at €1.6 billion, equally shared between the European Commission and industry, over the period 2008 – 2013. The objective of this unique public-private partnership is to speed up technological breakthrough developments and shorten the time to market for new solutions tested on Full Scale Demonstrators.

Speeding up new, greener design is essential to protect our environment. It should be kept in mind that aircraft have a 30-year service life, and that new aviation design takes more than a decade to develop. The accelerated research process that Clean Sky offers represents an unprecedented opportunity for rapid progress in the introduction of green technology into aviation.

Clean Sky will demonstrate and validate the technology breakthroughs that are necessary to make major steps towards the environmental goals sets by ACARE – Advisory Concil for Aeronautics Research in Europe – the European Technology Platform for Aeronautics & Air Transport and to be reached in 2020:
– 50% reduction of CO2 emissions through drastic reduction of fuel consumption
– 80% reduction of NOx (nitrogen oxide) emissions
– 50% reduction of external noise
– A green product life cycle: design, manufacturing, maintenance and disposal / recycling
The reduction goals set have the emissions of year 2000 as baseline.

Clean Sky 2
Clean Sky 2 will enable a natural continuation to the progress achieved in the first Clean Sky Programme launched under the EU’s 7th Framework Programme for Research and Technological Development (FP7), which will end in 2017. Projects in this first ground-breaking aeronautical JTI programme are delivering strong results – the potential for significant reductions in emissions, important noise reductions, and more efficient use of raw materials and finite resources.

Advancements in the first Clean Sky programme are mostly related to major components and large systems. The time is now ripe for moving towards their combination into complete aircraft demonstrators comprising innovative configurations. In addition to existing integrated technology demonstrators (ITDs), Clean Sky 2 will introduce further major demonstrations of several aircraft systems at the aircraft platform level. The technological improvements instilled by Clean Sky 2 will underpin innovative advances in the next generations of aircraft in time to meet the next market window to replace the current fleet.
Effectively fusing together the two phases of the Clean Sky JTI over a four-year transition period (2014-2017) will enable Europe to:
– Accelerate the development of smart, environment-friendly and energy-efficient aircraft which operate worldwide, thereby meeting environmental and societal targets for more efficient, safer and greener air transport.
– Achieve its strategic social priorities of sustainable growth, wealth creation and stable employment in fields of high technology.
– Win global leadership for European aeronautics with a competitive supply chain, which includes academia, research bodies and SMEs.
