ESTERA project is implemented under the CleanSky program. It is an initiative established under 7th Framework Programme of the European Commission and companies, which is a public-private venture. Leading european research institutes and companies in the airline industry are involved in the implementation of them. The emphasis is on participation in projects of small and medium-sized companies, as in the case of a ESTERA project. Actions taken by the Clean Sky have to contribute to the achievement of the goals set by ACARE (Advisory Council for Aeronautics Research in Europe) related to the reduction of CO2, NOX and noise. For these reasons, the involvement of the Clean Sky gives real reasons to use the project results in emerging aircraft construction.
