Abstract

The article focuses on analyzing the unsteady aerodynamic characteristics of multiple propellers in close proximity within distributed electric propulsion (DEP) configurations using a reformulated vortex particle method (rVPM). It distinguishes between noninterference and interference flow regions, finding that the middle propeller experiences greater performance fluctuations, especially in hover, while these fluctuations decrease with increasing advance ratio. The study also reveals that sideslip angles increase thrust coefficients and fluctuations, with the middle propeller most affected due to aerodynamic interference and downwash effects. These findings highlight the importance of considering unsteady aerodynamic interactions and propeller spacing in DEP design to balance aerodynamic efficiency, structural vibration, and noise.
