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/wingsread more

TL;DR: In this article, the authors investigated the non-linear behavior of the lift response of a pitch airfoil with a small amplitude and frequency where a linear behavior is expected, and the results shed light on the further enhancement of potential flow-based solutions to capture nonlinearity in the lift dynamics due to transition.

TL;DR: In this paper, the influence of the propeller location on the aerodynamic characteristics of a fixed wing MAV has been computationally investigated, and an actuator disk model with uniform pressure discontinuity, or disk loading, is employed to mitigate the computational requirement by reducing the unsteady three-dimensional flow-field around a propeller into a steady one.
