WebSep 15, 2024 · This paper experimentally investigates the propulsion of semi-active hydrofoils from wave energy. For the case of NACA 0012 foil section, heave amplitude h 0 = 1.0 chord, Reynolds number R e = 2 × 10 4, a series of flapping experiments were carried out.We examine the effects of the pivot location x p = 0.09c, 0.16c, 0.25c, and 0.33c on … WebFlapping-Wing Propulsion and Control. Flapping-wing NAVs and MAVs present significant propulsion and control challenges, and the development of these nano-flyers relies heavily on the field of biomimicry or biomimetics. When wings act as the means of both propulsion and control, successful vehicle integration requires an aerodynamic model for ...
