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

Modification of a longitudinal wind tunnel balance for identification of Micro Air Vehicle instabilities

TL;DR: In this paper, a longitudinal, load cell based wind tunnel balance was used for the measurement of lift and drag of the RIT Thnikkaman MAV and airfoils at near stall angles of attack.

Wing shape optimization design inspired by beetle hindwings in wind tunnel experiments.

TL;DR: In this paper, the wing shapes of three species of flighted beetles were designed in terms of the wing camber angle, geometry (including wing length, aspect ratio, and taper ratio), and wing area, to optimize lift together with the efficiency of wing.

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.
