ADVANCED FOIL DESIGN METHOD AND STRUCTURE FOR MULTI SPEEDS

Advanced foil design method and structure for multi speeds mainly adds a constraint according to a needed pressure distribution of the advanced foil after building an advanced foil environment. Thence, a step of optimization could be applied for analyzing the advanced foil by flow characteristics to achieve a shaped profile, so that a weight calculation weighted calculation would be further operated base on a proportion of the advanced coil applied to multi speeds. Accordingly, a preferable profile of the advanced foil and the environment parameter combination can be obtained to enhance a higher operative efficiency with the preferred benefit of the Supercavitating propeller while applied to a higher speed and with the profit of a stable competence while applied to a lower speed.
