Abstract It is known that the dynamic aeroelastic stability of T-tails dependent on steady aerodynamic forces at aircraft trim condition. Accounting for this dependency in flutter solution process involves correction methods doublet lattice method (DLM) unsteady aerodynamics, enhanced DLM algorithms, vortex (UVLM), or use CFD. However, improvements along with a commonly applied modal approach l...

In terrestrial vertebrates, the pelvic girdle can reliably predict locomotor mode. Because of the diminished gravitational effects on positively buoyant bony fish, the same relationship does not appear to exist. However, within the negatively buoyant elasmobranch fishes, benthic batoids employ pelvic fin bottom-walking and punting as primary or supplementary forms of locomotion. Therefore, in t...
