Abstract

View Video Presentation: https://doi.org/10.2514/6.2021-2625.vid In this work, computational fluid dynamics is used to perform safety analyses of rotors operating in ground effect. Initially, the paper focuses on the evaluation and prediction of the outwash generated by a micro-rotor operating at different heights above the ground. Time-averaged outflow velocities are compared with experimental results. Then, the simulated flowfield was used for safety studies using the PAXman model and particle tracking methods. The aircraft weights have been studied, evaluating scaling factors to define how the helicopter weight can affect the outflow forces and the particle paths. The The results show how the wake generated by heavier helicopters can lead to stronger forces on ground personnel and pushes the particles farther away from the rotor. Furthermore, the distance between the ground and the rotor has an influence on particle path, generating different dangerous scenarios for the aircraft crew and ground personnel.
