Scope

This Horizon Research and Innovation Action develops advanced, validated numerical and experimental aero-acoustic methods to predict the noise of new ultra-efficient aircraft designs, mainly large passenger aircraft with open fan engines and ultra-high bypass ratio architectures.

Focus

• Stronger fundamental understanding, closing of knowledge gaps and new or updated technologies that enable open fan designs.
• Technology building blocks for significantly reduced cabin noise.
• Existing and new experimental data and procedures, multidisciplinary design and optimisation, aerodynamics, aeroacoustics and noise-reducing metamaterials and structures.
• Optionally, better noise footprint assessment and better understanding and mitigation of annoyance.

Expected outcomes

Progress on airframe and cabin noise for new aircraft designs, engine noise sources and installation effects, and methods for noise perception, annoyance and mitigation. The work should build on lessons and gaps identified in earlier projects.

Kaj se pričakuje od predlogov?

• Proposals should build on lessons learnt and gaps identified in H2020.CS2-LPA-01-D01 and complement projects from HORIZON-CL5-2022-D5-01-12.
