| description | PROBLEM TO BE SOLVED: To provide a two rudder system which can improve propulsion efficiency by reducing rudder resistance, by a research in which a shape of a fin is considered.SOLUTION: A two rudder system comprises: a pair of rudder blades 111, 121 disposed on a rear side of one propulsion propeller 100; and a pair of fins 112, 122 protruding to a horizontal direction from inner broadside rudder faces of respective rudder blades 111, 121, in which the fins 112, 122 have a shape in which front edges 112a, 122a extend in a direction orthogonal to a shaft center of the propulsion propeller 100.SELECTED DRAWING: Figure 1
【課題】フィンの形状に着目した研究によって、舵抵抗を減じて推進効率の向上を図った二枚舵システムを提供する。【解決手段】一基の推進プロペラ１００の後方に配設する一対の舵ブレード１１１、１２１と、各舵ブレード１１１、１２１の内舷側舵面から水平方向に向けて張り出した一対のフィン１１２、１２２を備え、各フィン１１２、１２２は前縁１１２ａ、１２２ａが推進プロペラ１００の軸心と直交する方向に延びた形状をなす。【選択図】図１ |
