Analysis of Aerodynamic Interaction Due to Interference Effects Between Rotor, Ground and Obstacle
Year: 2024
Type: article
Abstract: Rotorcraft operating in urban environments can encounter aerodynamic instability caused by interference effects from the ground and obstacles.This study investigates these issues using computational fluid dynamics (CFD).Five comparative cases were analyzed, based on experimental cases involving scaled rotors and obstacles.The effects of obstacle presence and variations in distances between the ground, obstacles, and rotors were examined.The results revealed a sharp increase in rotor thrust due to ground effect and flow recirculation caused by back-flow.Such phenomena are expected to significantly reduce flight stability and reliability, posing substantial challenges to the operation of rotorcraft in urban areas.
