Aerodynamic interaction between propellers of a distributed-propulsion system in forward flight

Reynard de Vries et al.

Summary: This experimental study investigates the aerodynamic interaction between distributed propellers in forward flight, finding that adjacent propellers can affect performance and cause variations in local loading on the propeller disk. The interaction also leads to different noise waveforms, but active control of the relative blade phase angles between propellers can effectively modify the directivity pattern of the system.

Assessment of a Mid-Fidelity Numerical Approach for the Investigation of Tiltrotor Aerodynamics

Alex Zanotti et al.

Summary: This study investigates the performance and flow physics of tiltrotors using a new mid-fidelity aerodynamic code called DUST. Numerical simulations on XV-15 tiltrotor configurations show that DUST is suitable for capturing the complex aerodynamic interactions of tiltrotors.

Experimental Study of the Aerodynamic Interaction between Side-by-Side Propellers in eVTOL Airplane Mode through Stereoscopic Particle Image Velocimetry

Alex Zanotti

Summary: This article presents the results of a wind tunnel study on the aerodynamic interaction between side-by-side propellers in cruise flight conditions of eVTOLs. Stereo particle image velocimetry (PIV) measurements were used to provide detailed insights into the flow physics of the interacting propellers, focusing on the effects on tip vortices and wake topology at different advance ratios.
