title = "Application of active flow control to a generic low aspect-ratio trapezoidal wing for high lift generation",
abstract = "Fluidic oscillators located along the hinge of a flapped trapezoidal wing are used to augment the lift generated by such a planform. The semi-span model has an aspect ratio of 1.15 and a taper ratio of 0.27. The flap hinge spans the entire wing and it is parallel to the trailing edge. Experiments are performed in a low-speed wind tunnel at approximate Reynolds numbers of 1.7×106 over a wide range of incidence (-8° to 24°) and flap deflection angles (0° to 75°). The baseline flow on the deflected flap surface prior to total separation is oriented along the span (inboard) and its direction changes to outboard depending on incidence and flap deflection. The attached spanwise flow can be redirected, but most of the lift enhancement is realized when separation is avoided by the use of Active Flow Control (AFC). Integral force and moment results are supported by tuft flow visualization and pressure sensitive paint thus explaining the flow phenomena. In addition, the influence of non-uniform and high turbulence inflow on the efficacy of active flow control is investigated.",
