Computational Aeroelasticity Framework for Analyzing Flapping Wing Micro Air Vehicles [PDF]

open access: yesAIAA Journal, 2008
Due to their small size and flight regime, coupling of aerodynamics, structural dynamics, and flight dynamics is critical for Micro Aerial Vehicles. This paper presents a computational framework for simulating structural models of varied fidelity and a Navier-Stokes solver, aimed at simulating flapping and flexible wings.

Rotational accelerations stabilize leading edge vortices on revolving fly wings [PDF]

open access: yes, 2009
The aerodynamic performance of hovering insects is largely explained by the presence of a stably attached leading edge vortex (LEV) on top of their wings. Although LEVs have been visualized on real, physically modeled, and simulated insects, the physical
