Abstract
Description
船体の船首側に船舶の進行方向に突出して形成された前記流体流れ誘導板の流体流入口と、
船体の船尾側に形成された前記流体流れ誘導板の流体排出口と、
流体流入口と流体排出口を連結する流体移送通路とを、含む船舶の流体抵抗低減装置であって、
前記流体排出口は、流体流れ誘導板の内側に対向して付けられた弧形湾曲板によって、内径が縮小してから先端にいくほど流体流入口と同一の大きさに拡張される形状からなり、前記縮小した内径部に推進プロペラが設置されて、推進プロペラの回転力によって強制的に流入した海水が、先端にいくほど流体流入口と同一の大きさに拡張する流体排出口によって迅速な排出がなされるようにすることを特徴とする船舶の流体抵抗低減装置を提供する。
