Physical Phenomena Affecting the Dynamic Behavior of Fins

Abstract

One would arrive at the 'idealized' case by using the classic theory of air-foils in steady motion in an unbounded medium; by assuming the ship's velocity to be always the same; by assuming that the capacity of the system is never exceeded; and by making a one-degree-of-freedom assumption for the ship (which last is not commented on in this memo). This paper discusses four complications or additional phenomena, which affect the actual dynamic behavior of fins: (1) The Velocity Effect; (2) The Free-Surface Effect; (3) Cavitation Effects; (4) Unsteady Motion Effects.
