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

Static Aerodynamic Loading and Stability Considerations for a Micro Aerial Vehicle

TL;DR: In this article, the Model Positioning System (MPS) is used to simulate the flight of a micro aerial vehicle (MAV) in order to determine the passive stability of the vehicle.

Aerodynamic efficiency of gliding birds vs comparable UAVs: a review

TL;DR: There is no definitive evidence that any gliding bird species is either more or less efficient than a comparable UAV, but species flying within subcritical Reynolds number regimes may inspire UAV designs that can extend their operational range to efficiently operate in subcritical regimes.

Extracting Aerodynamic Coefficients using Direct Trajectory Sampling

TL;DR: In this paper, a technique to extract aerodynamic characteristics of an aircraft directly from collected trajectories is described, which takes advantage of a vision tracking system that dispenses with any on-board navigation sensors and the stationary atmospheric conditions prevailing in the indoor flight experiment facility used to collect flight data.

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.
