Rotor wake interactions with an obstacle on the ground [PDF]
, 2018 An investigation of the flow around an obstacle positioned within the wake of a rotor is described. A flow visualisation survey was performed using a smoke wand and particle image velocimetry, and surface pressure measurements on the obstacle were taken.

Using piloted simulation to measure pilot workload of landing a helicopter on a small ship [PDF]
, 2017 When conducting landings to a ship's deck in strong winds, helicopter pilot workload is often dominated by the turbulence within the ship's airwake. Previous studies have shown that larger ships create more aggressive airwakes and simulated flight trials
