A buyer is seeking noise reduction breakthroughs for new ultraefficient aircraft. The goal is to achieve advancements in this area. The project involves developing solutions for noise reduction in aircraft.
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. The topic should reinforce fundamental understanding, fill gaps and propose new/updated technologies towards enabling open fan designs and techno bricks for significantly reduced cabin noise. Mayor emphasis is expected to be put to existing/new experimental data and procedures, multi-disciplinary design and optimisation, aerodynamics, aeroacoustics and noise reduction integrated metamaterials/structures. In addition, the proposals may also provide even better noise footprint assessments and better annoyance understanding and mitigation methodologies. The topic should build upon lessons learnt and gaps identified from H2020.CS2-LPA-01-D01 as well as complementing the projects resulted from HORIZON-CL5-2022-D5-01-12.
