LOW DRAG SUBMERGED ASYMMETRIC DISPLACEMENT LIFTING BODY, WATERCRAFT INCLUDING THE SAME AND WATERCRAFT HULL HAVING THE SAME

摘要

Low drag underwater submerged lifting bodies which can be used as underwater displacement portions of a vessel whose main hull is at sea level are asymmetrical and have improved lift to drag ratios. The lifting bodies have outer surfaces whose shapes are defined in plan and elevation by generally parabolic curves which are different on opposite sides of the lifting bodies.
