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...

Natural gas hydrates represent a vast energy resource, yet their formation in fine-grained sediments remains poorly constrained. Here, CH4 hydrate growth in a quartz sand column with distinct geometries, solid versus hollow, was measured at an initial pressure of 6 MPa and temperatures ranging from 274.15 to 278.15 K...

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...
