Abstract

Urban aerial mobility (UAM) is a promising solution for future urban traffic. Environmental noise is a development constraint for the use of UAM aerial vehicles. This paper summarises the research activities on UAM, including experimental measurements, numerical simulations, and theoretical modelling, in the Aerodynamics and Acoustics & Noise Control Technology Centre (AANTC). Fundamental acoustics physics of the UAM noise including generation, scattering, outdoor propagation and perception are studied, aiming at developing low-noise UAM designs and quiet flight planning. Notably, the measurements in anechoic facilities and simulations on high-performance supercomputers can lead to a comprehensive database to facilitate and validate physics-oriented noise prediction models. The sound scattering, depending on fuselage configuration and propulsion system arrangement, is estimated using an efficient boundary element method. The noise radiation is efficiently projected to the far-field environment using an advanced Gaussian beam tracing method. A hexa-rotor UAM flying in an urban region is studied to demonstrate the key elements and capacities of the research platform, based on which UAM noise assessment and low-noise designs can be conducted efficiently. © INTER-NOISE 2021 .All right reserved.
