Unsteady aerodynamic forces of a flapping wing [PDF]
Journal of Experimental Biology, 2004 SUMMARYThe unsteady aerodynamic forces of a model fruit fly wing in flapping motion were investigated by numerically solving the Navier–Stokes equations. The flapping motion consisted of translation and rotation [the translation velocity (ut) varied according to the simple harmonic function (SHF), and the rotation was confined to a short period around ...

Unsteady aerodynamics of nonslender delta wings [PDF]
Progress in Aerospace Sciences, 2005 Unsteady aerodynamics of nonslender delta wings, covering topics of shear layer instabilities, structure of nonslender vortices, breakdown, maneuvering wings, and fluid/structure interactions, are reviewed in this paper. Vortical flows develop at very low angles of attack, and form close to the wing surface. This results in strong interactions with the
