Noise reduction breakthroughs for new ultraefficient aircraft

Overview

Funding for advanced research and development of noise reduction technologies in next-generation ultraefficient aircraft, targeting large passenger aircraft with open fan or ultra-high bypass ratio engine architectures. Intended for consortia or organizations with expertise in aeroacoustics, aerodynamics, and noise mitigation methodologies.

Who Can Apply

Eligible applicants include legal entities established in EU Member States, Horizon Europe Associated Countries, or other non-EU/non-associated countries with specific funding provisions. Consortia are expected, involving industry, research organizations, and academia.
