Pitch-plunging flat Wings in Experiments and Numerical Investigations

摘要

This paper presents the first results of a broad study of static and moving flat plate wings for Micro Areal Vehicles, (MAV). Wind tunnel experiments with force measurements were performed in a specially designed wind tunnel environment for low Reynolds number investigations. Corresponding numerical flow simulations were also carried out. Effects of the wing shape (elliptical and rectangular), the aspect ratio (1 and 2), the Reynolds number (18.000, 36.000 and 108.000) and the kinematics using different motion forms of pure plunge and combined pitch/plunge with a reduced frequency of k=0.2 are discussed.
