Projecto Clean Sky
1) The document discusses ACARE (Advisory Council for Aeronautics Research in Europe) and its Clean Sky initiative, a public-private partnership between the European Commission and industry aimed at developing more environmentally friendly air transportation technologies. 2) Through integrated technology demonstrators, Clean Sky aims to significantly reduce aircraft emissions, noise, and fuel consumption by 2020 compared to 2000 levels. Targets include 50% reduction in CO2, 80% reduction in NOx, and 50% reduction in noise. 3) Expected results from Clean Sky include technologies for reduced fuel consumption such as efficient engines, lightweight structures, and improved aerodynamics. It also focuses on reducing external noise through engine and airframe design
