Simplified eVTOL aeroacoustic assays – Semi-anechoic chamber assay

14/12/2021 10:21

Description: The project aims to perform noise measurements of simplified models of eVTOL type aircraft. The tests are conducted in the semi-anechoic chamber of the Laboratory of Vibrations and Acoustics. The current setup allows for tests with insulated propellers, covering ranges of propeller diameters and typical application rotation speeds for small drones. New bench configurations are under development to assess the helix installation effect and the effect of acoustic interaction of multiple rotors.

Coordinator/ Participants: Prof. Júlio Apolinário Cordioli (coordinator); M. Eng. Lucas Araújo Bonomo (participant/LVA UFSC); Eng. Marcelo Henrique Martinelli Martins (participant/ LVA UFSC); Isabela Canello Resener (participant/ LVA UFSC); Nicolas T. Quintino (participant/ LVA UFSC); Prof. Andrey Ricardo da Silva (collaborator/ LVA UFSC).

Partners: EMBRAER
