TOROIDAL RECIRCULATION, SADDLE-POINT TOPOLOGY, AND WALL-JET OUTWASH IN A TWIN-ROTOR SYSTEM IN GROUND EFFECT
N. Pradyumna¹, M. Li¹, D. Verstraete¹; ¹The University of Sydney, Australia
This study investigates rotor wake development in ground effect using Particle Image Velocimetry, focusing on the influence of blade pitch and blade count. The results provide quantitative insight into near-ground outwash and wall-jet formation, directly supporting eVTOL certification, vertiport safety assessment, and rotor design for urban operations.
