TLDR
In this paper, the authors measured the lift, drag, and pitching moment about the quarter chord on a series of thin flat plates and cambered plates at chord Reynolds numbers varying between 60,000 and 200,000.
Abstract
The design of micro aerial vehicles requires a better understanding of the aerodynamics of small low-aspect-ratio wings An experimental investigation has focused on measuring the lift, drag, and pitching moment about the quarter chord on a series of thin flat plates and cambered plates at chord Reynolds numbers varying between 60,000 and 200,000 Results show that the cambered plates offer better aerodynamic characteristics and performance It also appears that the trailing-edge geometry of the wings and the turbulence intensity in the wind tunnel do not have a strong effect on the lift and drag for thin wings at low Reynolds numbers Moreover, the results did not show the presence of any hysteresis, which is usually observed with thick airfoils/wings

Preset angle, aspect ratio, and stall representations effects on the aeroelastic responses of small-scale wind turbine blades

TL;DR: In this article , the effect of the preset angle on the blade stability was investigated by jointly performing linear analyses that provided insights on this parameter's influence on the onset of flutter, accompanied with nonlinear analyses that evaluated the latter design parameter's effect on blade bending and torsion amplitudes in the post-flutter regime.

Experimental Time Resolved Flow Features of Separation Over an Elliptic Leading Edge

TL;DR: In this article, the flow conditions are characterized by low Reynolds flow at two relatively high angles of attack, 15° and 20°, and a high pass Gaussian filter was employed to help identify structures within the flow field.

Wind tunnel tests of wings at Reynolds numbers below 70 000

TL;DR: In this article, a planform wing was tested at Reynolds numbers as low as 20 000 in a low turbulence wind tunnel and the best profile was a thin plate with a 5% circular arc camber.
