The increasing focus on sustainability and the need to develop less polluting aircraft models have led to the emergence of Distributed Electric Propulsion (DEP) aircraft as a revolutionary solution. The utilization of DEP systems has gained considerable traction in Electrical Vertical Take-Off and Landing (eVTOL) aircraft for urban and military applications in the modern era. These new vehicles, known for their versatility, efficiency, and technological innovation, require a detailed analysis of rotor configurations, generated noise, and performance impact. This research aims to investigate the wake development and propeller interactions in DEP systems for urban air mobility (UAM) vehicles. Specifically, the study focuses on the interaction of two side-by-side rotors positioned along the wing of the eVTOL VX4 vehicle produced by Vertical Aerospace, analyzing the evolution of tip vortices under both hover and forward flight configurations.
