| Abstract: | This paper represents an experimental study on the aeroacoustics behaviours of multi propellers. Two propellers are distributed in various spatial configurations to mimic some of the configurations that resemble a typical eVTOL (electrical Vertical Take-Off and Landing) aircraft. The interdependence for various influencing parameters for the acoustic radiations, such as the longitudinal and transverse displacements between a reference propeller and another propeller, as well as the different rotational speeds, was investigated in a specially constructed test rig inside an anechoic chamber under a quiescent condition. Statistical quantities such as the power spectral density and overall sound pressure level are presented. |
