The invention provides a novel low-resistance bilge keel structure of a maritime work auxiliary ship. The structure comprises a conventional bilge keel fixed to a bilge of a ship body and a pluralityof discrete leaf-shaped rotatable bilge keels. According to the novel low-resistance bilge keel structure of the maritime work auxiliary ship, the part, inconsistent with the surface streamline of theship body due to the situation, of a conventional bilge keel is removed and replaced with a plurality of discrete leaf-shaped bilge keel structures capable of rotating within a small angle range, andthe angles of the discrete leaf-shaped bilge keel structures are automatically adjusted along a streamline during sailing, so that the resistance is reduced.
本发明提供一种新型海工辅助船低阻力舭龙骨结构,包括固定于一船体的舭部的常规舭龙骨和多个离散式叶形可旋转舭龙骨。本发明的一种新型海工辅助船低阻力舭龙骨结构,将常规舭龙骨中会因上述情况而与船体表面流线不一致的部分去掉,用能够在较小角度范围内转动的多个离散式叶形舭龙骨结构代替;这些离散的叶形舭龙骨结构在航行的时候自动沿流线调整角度,从而减小阻力。
