Mast wake reduction by shaping |
摘要 |
A mast for use on a submarine is disclosed. The shape of the mast includes a sharp leading edge. The leading edge widens to an angle greater than the maximum angle of angle of attack that the mast will experience during maneuvering. The shape produces a stagnation zone that minimizes flow separations at the bow wave and has a pressure coefficient that approaches zero such that wake signatures of the mast are reduced. The surface of the mast is roughened to be capable of producing a turbulent boundary layer of the mast further reducing wake signatures from the bow wake.
