共舵軸心より前縁に対して舵に当る推力流入射角相当の
角度を与え舵巾前半を半月型と後半従来蛇形状の組合せ
により不対称翼型流線型とし上下直線前縁及び彎曲起点
は対称翼型とした三ツの異る断面を有する舵構造。Only the part of the leading edge of the front surface of the rudder that is affected by the thrust flow is divided upward and downward from the thruster axis line, and the front line is curved in the direction of the thrust inflow and incidence angle. The blade is curved for restoration and is not affected by the thrust flow.The curved ends and the upper and lower straight leading edges are connected near the 1° ID, and the curved shape with the upper and lower starting points together is S-shaped or inverted S-shaped depending on the direction of blade rotation. S
The cross section of the wing at the 0.75 D position, which is the maximum curve of the shape, has an angle equivalent to the thrust inflow and incidence angle that hits the rudder from the rudder axis to the leading edge of both the upper and lower rudders, and the first half of the rudder width is half-moon-shaped and the second half is conventionally snake-shaped. The rudder structure has three different cross sections, with a streamlined asymmetrical airfoil, a symmetrical airfoil with a straight leading edge at the top and bottom, and a curved starting point.
