Abstract

The dynamics of a free pitching flexible cantilever NACA 0012 airfoil were investigated at transitional Reynolds numbers. This work builds on previous investigations based on a quasi-2D rigid wing, moving elastically in pitch and heave. Wind tunnel tests were performed at various speeds, and three limit cycle oscillation (LCO) branches were observed. Further work is required to supplement this preliminary analysis, such as modeling, FEA simulation, and evaluation of the strain and acceleration information of the wing deformation
