This dataset contains the data required to reproduce the results in the journal article: "The effect of turbulence on a flexible finite wing: forces, deflections and the wingtip vortex". It contains experimental results obtained in the wake of a flexible finite wing, specifically capturing the wing tip vortex, at different turbulent conditions set using an active turbulence grid. The wing tip vortex was captured using cross-stream stereoscopic particle image velocimetry (PIV). Digital Image Correlation (DIC) was employed to study the deformation of the flexible wing under the different turbulent conditions. The performance of the wing (lift and drag) was measured using a force balance. Characterisation of the turbulent freestream generated by the active grid was carried out using hot-wire anemometry (HWA).
