European manufacturers studying green helicopters

The European helicopter industry has until February 23 to answer a call for proposals under the Clean Sky joint technology initiative, a public-private partnership aimed at making aviation greener. The initiative comprises six integrated technology demonstrators, one of them called Green Rotorcraft. Targets include reductions in noise, carbon dioxide (CO2) and pollutant emissions.

The most recently issued call for proposals included development of computational tools that would provide laminar airflow on main rotor blades. This is one way to cut fuel burn. Maximum budget for this is €130,000 ($190,000).
