BATTERIES and MOBILITY · Noise reduction breakthroughs for new ultraefficient aircraft

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.

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…
