TL;DR: In this paper, a water tunnel study of the effect of spanwise flexibility on the thrust, lift and propulsive efficiency of a rectangular wing oscillating in pure heave has been performed.

TL;DR: In this article, an experimental study of unsteady aerodynamics of two-dimensional membrane airfoils at low Reynolds numbers was conducted, where the amplitude and mode of the vibrations of the membrane depend on the relative location and the magnitude of the unsteadiness of the separated shear layer.

TL;DR: In this paper, a review of vortex control concepts employed for slender and nonslender delta wings were reviewed, and various flow control methods were discussed: multiple vortices, control surfaces, blowing and suction, lowfrequency and high-frequency excitation, feedback control, passive control with wing flexibility, and plasma actuators.

TL;DR: In this paper, two side-by-side cylinders with fixed support at both ends placed in a cross-flow were experimentally investigated, where two fibre-optic Bragg grating sensors were used to measure the dynamic strain, while a hot wire and flow visualization were employed to examine the flow field around the cylinders.

TL;DR: In this paper, a review of vortex control concepts employed for slender and nonslender delta wings were reviewed. Important aspects of flow control include flow separation, vortex formation, flow reattachment, vortex breakdown, and vortex instabilities.
