Drone noise mitigation is a key enabler for urban air mobility technology adoption. Noise pollution is one of the main reasons why helicopter operations are often restricted. Thanks to the distributed electrical propulsion architecture, eVTOL air taxis and drones offer a perspective to reduce sound levels by 15dB at 500ft compared with helicopters.
Achieving this objective is critical to decreasing the overall journey time and thereby increasing the overall attractiveness of this new mobility mode. The challenge at hand is to design disc loading, rotor tip speed, propellor interactions and vehicle scattering in such a way that the overall in-situ noise levels are reduced.
It is a multidisciplinary issue, calling for the combined use of various simulation and testing techniques.
