Noise reduction breakthroughs for new ultraefficient aircraft

Horizon Europe forthcoming topic HORIZON-CL5-2027-04-Two-Stage-D5-09 (call HORIZON-CL5-2027-04-Two-Stage). Opens on 15 December 2026. Deadline 14 April 2027, 17:00 Brussels time; the call page lists every cut-off. Expected Outcome: Project results are expected to contribute to all of the following expected outcomes: Airframe / cabin noise for new aircraft design; Engine noise sources and installation effects; Noise perception/annoyance and mitigation methodologies. Scope: The topic aims to deliver advanced and validated numerical and experimental aero-acoustic methodologies for the noise prediction of new ultraefficient aircraft designs, primarily for large passenger aircraft with new open fan engine architectures and ultra-high by-pass ratio architectures.
