Pursuing a quieter future in civil aviation

Winkler et al talk about civil aviation. In the field of urban air mobility noise, researchers at the University of Cincinnati's Advanced Mobility Propulsion Lab conducted novel flow-field experiments on an electrically driven propulsor in March. The University of California, Davis extended the capabilities of the physics-based rotor broadband noise prediction tool UCD-QuietFly by coupling it with high-fidelity computational fluid dynamics under a Nov 2021 contract with Washington DC-based Supernal, with plans to develop low-noise propeller designs using this computational tool.
