Hydro-foil float for subsonic or supersonic aircraft - has two parabolic and triangular thin weight supporting surfaces acting as keel

摘要

The hydro-foil comprises a central body (50) which supports the useful load, together with an integral supporting surface (52) on each side. These supporting surfaces form fins and are very thin, each float tapering to a rounded nose (51) and widening to form a triangular structure (54). The cross-section of each fin is based on the parabola, forming rounded profiles which are very rigid and counteract the effects of vibration. Vanes.
