SENECA - (LTO) noiSe and EmissioNs of supErsoniC Aircraft

In SENECA, eleven academic and industrial aerospace entities from all over Europe have teamed up to address the challenges raised in the call LC-MG-1-15-2020 “Towards global environmental regulation of supersonic aviation”. The consortium is considering the forthcoming market entry of a new generation of supersonic aircraft. However, it is assumed that the first new generation of supersonic aircraft will not be able to fly over land with supersonic speed, i.e. will not have completely solved the problem of the supersonic boom. Therefore, the missions under consideration for this project will be supersonic over water and subsonic over land. As a consequence, SENECA will mainly focus on noise and emissions in the vicinity of airports and the global climate impact of supersonic aircraft. SENECA aims at developing deepened understanding and detailed modelling for the emissions, the LTO noise, and the global environmental impact of supersonic aircraft. Building on this, the development of beyond state-of-the-art technologies to further reduce the environmental impact of supersonic aviation will be enabled. SENECA will contribute its project results to the ICAO level discussions, in order to scientifically accompany and strengthen the European perspective on the necessary regulations for novel supersonic aircraft. Key milestones of the project dissemination and exploitation plan are aligned to the CAEP work program and agenda, and the whole project plan is designed to work towards these milestones.
