Unsteady Low-Reynolds Number Aerodynamics for Micro Air Vehicles (MAVs)

Abstract

This report documents recent progress in in-house research in the AFRL Air Vehicles Directorate on unsteady aerodynamics at low Reynolds number. The application is the aerodynamics and flight dynamics of agile Micro Air Vehicles, to include flapping-wings. Experiments included quantitative and qualitative flowfield velocimetry on the Selig SD7003 airfoil, undergoing a range of harmonic and ramp motions in two degrees of freedom - that is, pitch and plunge. Relevant classical results in the literature have been confirmed, with new results on spanwise flow in the starting-vortex for plunge motions of high reduced frequency.
