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

A Novel, Low Reynolds Number Moment Balance Design for Micro Air Vehicle Research
Kevin Kochersberger,Corey Abe +1 more
TL;DR: A simple mechanical balance was designed to measure both pitch and roll moments and several small scale flat plates and cambered airfoils are used to statistically evaluate the performance of the mechanical balance system.
Low Reynolds Number Airfoil Evaluation for the Mars Helicopter Rotor
TL;DR: In this article, a RANS-based approach is used to generate the airfoil deck using overflowing with stitched experimental data for very high angles of attack, and a performance model for the MH rotor for a free wake analysis is presented.

Flow transitions on a cambered airfoil at moderate Reynolds number
TL;DR: In this paper, a combined experimental and numerical study is performed to investigate the flow field and associated aerodynamic forces on a cambered airfoil, and the results show that the Reynolds number is low enough to ensure importance of viscous dynamics, and high enough so that instability and transition to turbulence can occur.

Lift and drag characteristics of a cascade of flat plates in a configuration of interest for a tidal current energy converter: Numerical simulations analysis
TL;DR: In this paper, numerical simulations of the three-dimensional flow through a cascade of flat plates are conducted to analyze their lift and drag characteristics in a configuration of interest for a particular type of tidal hydrokinetic energy converter.
Impacts of rudder configurations on inland vessel manoeuvrability
TL;DR: In this article, an integrated manoeuvring model for both seagoing and inland vessels has been proposed and validated for both the seagoer and the inland vessel, and the impact of different rudder configurations on ship manoeuvrability has been investigated.

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.
