By hosting the Aerodays show, London has become the European capital of aeronautics research and innovation, and concerning the subject; it is impossible to miss Clean Sky. Since 2008, this ambitious European public–private partnership (PPP) programme has the aim of giving a real boost to developing new cleaner aviation technologies.
To reduce aircraft fuel consumption, and therefore CO2 emissions, the Open Rotor, for example, a jet engine without nacelle is being studied, as are all electrical systems that will replace existing hydraulic or pneumatic systems. The development of lighter materials and hybrid propulsion systems are also other possibilities.
Eric Dautriat, Clean Sky Program Executive Director: interview in the video.
The second phase of the research programme (Clean Sky 2) was launched in 2014, and in order to achieve its mission, involving 4,000 people, it has a budget of four billion euros, half of which is financed by the European Union, and the other half by aviation sector manufacturers. Its goal is clear: that of reducing, by half, aircraft generated CO2 emissions and noise by 2020 (compared to 2000).
