Z-Fold Wing Aeroelasticity: Compositional Modeling, 1:2 Double-Hopf Dynamics, and Nonlinear Stiffness Effects

Folding changes the linearized aeroelastic spectrum and can switch which mode becomes unstable first, with consequences for local postflutter interactions. This study formulates a three-component Z-fold wing by assigning every aerodynamic station to a structural component and a material coordinate. The same attachment...

Flutter Analysis for Folding-Wing Aircraft Considering Rigid–Flexible Coupling

Folding-wing aircraft, a category of morphing aircraft, enhance multimission adaptability through wing configuration changes. However, they face a critical flight safety issue: aeroelastic stability during dynamic morphing processes. This paper investigates aeroservoelastic modeling, flutter analysis, and control strat...
