The AeroAcoustics Research Consortium (AARC) held its annual year-end review on Monday, October 7, 2024, at the Ohio Aerospace Institute in Cleveland, Ohio. The hybrid event was attended by 25 in-person and ten virtual participants from seven countries. Through the meeting, members reviewed progress on supported projects and had the opportunity to interact with leading researchers in the field.
At this year’s review, five technical presentations were featured with projects supported by AARC, followed by an in-person meeting of the consortium’s peer review panel. Research topics included: methods for decomposing aircraft engine noise measurements into separate source components, the impact of sustainable aviation fuels (SAFs) on combustion noise and modeling, and simulation and experimental measurement of sound-absorbing acoustic liners in the presence of flow.
The AARC is a collaborative partnership between NASA and industry members, Airbus, Honeywell Aerospace, Pratt & Whitney and Rolls-Royce, with The Ohio Aerospace Institute (OAI) serving as administrator and Dr. Stewart J. Leib as the Director. The goal of the consortium is to advance pre-competitive research and development in aeroacoustics for the benefit of its members. The consortium supports research projects selected by its members from internationally recognized researchers, sponsors technical workshops in areas of interest, and holds the annual year-end review.
Membership in the AARC provides participants with an international collaborative environment in which to push boundaries on common barrier problems without regard for individual company product lines.
Results from supported research is typically published in peer-reviewed journals and presented at international conferences, benefitting the industry at large. Direct interactions with researchers and reports, presentation slides and technical data is limited to members, providing them with additional value.
The AARC has a history of supporting student research through financial contributions toward the prize awarded for the American Institute of Aeronautics and Astronautics/Council of European Aerospace Societies (AIAA/CEAS) Best Student Paper Award in Aeroacoustics. This year’s award winner, Levent Ugur of University of Bristol, was announced at the AIAA/CEAS Aeroacoustics Conference in Rome in June, and an acknowledgement of AARC’s contribution was made at the conference.
