Short abstract: Discrete vortical gusts with different strengths and trajectories were generated and characterized using Time Resolved Particle Image Velocimetry (TR-PIV) in the University of Dayton Water Tunnel (UD-Wat). The discrete vortical gusts were generated by rapidly pitching a flat plate about its quarter chord.

Short abstract: The open and closed-loop response of a wing to discrete vortical gusts of differing strengths was characterized using Time Resolved Particle Image Velocimetry (TR-PIV) in the University of Dayton Water Tunnel (UD-WaT). Discrete vortical gusts were generated by rapidly pitching a flat plate gust generator upstream of the wing.

Short abstract: The generation and evolution of a discrete vortex was simulated using unsteady panel method and the results were compared with PIV measurements in a field of view 5 chords downstream of the gust generator. The dynamics of the discrete vortex gust encounter of an SD7003 wing were studied across a span of angles of attack.
