Research on silent aircraft concepts (ROSAS)

Ziel

As a complement to the on-going research and development efforts deployed by the European aeronautical community towards the reduction of civil aircraft noise, efforts which focus on reducing noise emitted at the source by the engine and the airframe like in RAIN and SILENCE(R) programmes, the ROSAS proposal aims at developing the necessary capabilities for the evaluation and selection of innovative silent aircraft concepts, characterized by the shielding of the engine noise sources by the airframe components (wing/fuselage/empennage). ROSAS tackles the main critical issues of alternative installations of advanced turbofan engines through acoustic experimental and theoretical investigations, including a wind tunnel test campaign, and CFD-based aerodynamic work to identify the key phenomena and related risks and achieve an efficient shape design in the power plant area. This will be completed with a multi-disciplinary evaluation of the innovative concepts in order to achieve a fair comparison with the conventional underling engine installation.
