Aeroelastic oscillations of a pitching cantilever wing with structural geometric nonlinearities: theory, numerical simulation and global sensitivity analysis

Abstract: The focus of this thesis is the aeroelastic dynamics of a rectangular cantilever wing with a NACA 0012 profile, whose base is free to rotate rigidly about a longitudinal axis. The wing is analytically modelled as part of a project to simulate the dynamics of an aeroelastic wind tunnel model.Structural geometric nonlinearities are modelled to the second order to capture the essential effects of large deformation. While the derivation closely follows common approaches from the literature on the subject of the no… Show more

“…Additionally, C L , C D , C M are the aerodynamic coefficients of lift and drag forces, and pitching moment at the aerodynamic center (AC), respectively. In general, the AC is located at the quarter of chord length from the leading edge in the case of a subsonic flow (which is the type of flow used in this study), as presented in Figure 3.5 [55]. The AC is shifted to half chord point for a supersonic flow [55].…”

“…In general, the AC is located at the quarter of chord length from the leading edge in the case of a subsonic flow (which is the type of flow used in this study), as presented in Figure 3.5 [55]. The AC is shifted to half chord point for a supersonic flow [55]. By definition, the aerodynamic moment is independent of the angle of attack at the AC, and is equal to 0 for symmetrical airfoils under a subsonic flow [50].…”
