船体10内から供給される。Note that the rudder plate 11 is divided into a movable rudder plate 27 and a fixed rudder plate 15. A movable rudder plate 27 formed in a substantially U-shape is rotatably supported by a rudder shaft 17 hanging downward from the stern. The fixed rudder plate 15 is engaged with the recess of the movable rudder plate 27 and fixed to the rudder shaft 17. 18 is a rudder handle for operating the movable rudder plate 27. A motor 19 as a drive source is attached inside the fixed steering plate 15 and connected to a drive shaft 16 extending forward from the fixed steering plate 15. The motor 19 is of a hydraulic type or an electric type, and its power source is supplied from inside the hull 10 through a hollow hole 20 provided in the rudder shaft 17.

じる。前部プロペラ12と逆に回転している後部プロペ
ラ13に流入する回転流は後部プロペラ13に回転のエ
ネルギーを吸収され、平行流となって後方へ流出する。When seawater flows into the vicinity of the front propeller 12, the rotation of the propeller 12 generates a rotational flow accompanied by twisting as a wake. The rotating flow flowing into the rear propeller 13, which rotates in the opposite direction to the front propeller 12, has its rotational energy absorbed by the rear propeller 13, becomes a parallel flow, and flows rearward.
これにより回転のエネルギーをスラストとして有効に回
収することができ、船の斜行性もなくなる。This allows the rotational energy to be effectively recovered as thrust, and eliminates the ship's oblique behavior.
