Comparison of the Aerodynamic Characteristics of the NACA0012 Airfoil at Low-to-Moderate Reynolds Numbers for any Aspect Ratio
TL;DR: In this paper, the influence of the angle of attack (AoA) and the chord based Reynolds number (Rec) on the lift and drag coefficients for a low-aspect-ratio NACA0012 airfoil was investigated.

Low-to-moderate aspect ratio wings tested at low Reynolds numbers
Abstract: This paper presents wind tunnel results of wings of low-to-moderate aspect ratio (2≤A≤5) at low Reynolds numbers (60,000 to 160,000). Tests were conducted in the low-turbulence wind tunnel in the Subsonic Aerodynamics Research Laboratory at the University of Illinois at Urbana-Champaign (UIUC). A 3-component force/moment balance was designed and fabricated. The balance design methodology and validation are described in detail. Low Reynolds number tests performed on a wing having an aspect ratio of 4 and using the Wortmann FX 63-137 airfoil showed the existence of a critical Reynolds number of 90,000 for which a jump in performance characteristics was observed. Pre-stall and post-stall hysteresis was captured at the critical Reynolds number. Flow visualization photographs for the wing at different angles of attacks are presented. Finally, aerodynamic performance measurements taken for ten flat-plate rectangular and tapered wings are also presented and discussed.

Simulation of Flight Dynamics with an Improved Post-Stall Aerodynamics Model
TL;DR: In this article, a post-stall aerodynamic prediction method was developed for real-time simulation of aircraft flight dynamics. But this method does not handle the effects of bodies, propeller-wash, and wake interference.
