HYDRODYNAMIC CHARACTERISTICS OF A CONTROL SURFACE

A study of the performance of a low-aspect-ratio, all-movable control surface in water is presented and compared with the performance of similar control surfaces in air. The results of this study show the free-stream characteristics of a control surface with an NACA 0015 section and a 45 percent taper ratio for different conditions affecting cavitation and stall. It is concluded that large angles of attack should be avoided under conditions that may cause stall. (Author)
