发明名称 Base vented subcavitating hydrofoil section
摘要 A "fish-shaped" hydrofoil section and in particular, a hydrofoil section having a body of cross-sectional area increasing in thickness from the leading edge to a point near the midchord of the hydrofoil section. The thickness of the body then decreasing some amount to a local minimum, and thereafter increasing along concave surfaces in a "fishtail" flare to a local maximum thickness at the trailing edge. A low pressure area develops behind the trailing edge of the "fishtail" flare and is ventilated with gas at a pressure greater than that of the developed low pressure area. The cross-sectional shape of the hydrofoil section can be symmetrical or cambered.
