Noise is not just an engineering problem; it’s a human problem. The Advanced Mobility Propulsion Lab aims to develop novel data, tools, designs, and solutions for ultra-quiet electric aircraft propulsion systems. The novel aircraft envisioned by Advanced Air Mobility (AAM) and Unmanned Aerial Systems (UAS) present unique aerodynamic and aeroacoustic challenges. Distributed electric propulsion (DEP) is introducing a new class of aircraft with up to 30 propulsors per aircraft. Existing acoustic prediction tools, noise models, acoustic metrics, and noise regulations are insufficient to ensure that AAM noise impact will be publicly acceptable in urban, suburban, and rural communities. We collaborate with leading electric aircraft companies, DoD partners, government agencies, and small businesses to develop comprehensive solutions that enhance community possibilities without increasing noise annoyance.
