The measurements of lift coefficient and liftcurve slope are presented. The results were obtained from tests and integrations of surface static-pressure data over a model of the NACA 0012 airfoil section. Data for the NACA 0012 airfoil were obtained for a free-stream Mach number range of 0.25 ...
Specifically, we apply the Force Partitioning Method (FPM) to correlate flow features with lift production, which helps understand characteristic trends in the lift curve, including shift from negative to positive lift and slope breaks. The remainder of the paper is structured as follows. First, ...

Based on the inputs from previous simulation, various design modifications are adopted like addition of flap at different angles, slots at leading and trailing edge and finally gurney flap with a supporting wedge structure in order to analyze their impact on lift and drag coefficients. Finally, ...
