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

Aerodynamic Coefficients and Deformation Measurements on Flexible Micro Air Vehicle Wings

TL;DR: In this article, the elastic deformations and corresponding aerodynamic coefficients of flexible wings used for micro air vehicles (MAVs) were evaluated in a low-speed wind tunnel facility integrating a visual image correlation (VIC) system with a six-component strain gauge sting balance.

Design, Analysis and Hover Performance of a Rotary Wing Micro Air Vehicle

TL;DR: Results from this initial feasibility study suggest that it is possible to develop a small scale coaxial micro rotorcraft weighing approximately 100 grams, and that available moments are appropriate for roll, yaw and lateral control.

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.
