Conventionally, as this type of rudder structure, the one shown in FIG. 1 is known. On the downstream side of the screw propeller b, the propeller wake generated by this propeller has a blade shape along the ship's ship's direction, and is formed by expanding vertically in the depth direction of the ship, and mainly protects the ship's hull. A rudder plate c is provided that generates lift for the purpose of turning. This snake plate c is rotatably supported by a rudder horn d hanging from the stern a. As shown in Fig. 2, the rudder plate c, which is rotated as appropriate during these turns, and the rudder horn d, which is the pivot of the rudder plate c, form a series of wing shapes, and these are connected to the hull. When driving straight, the screw
Axial flow generated by the rotation of propeller b
A lift force L is generated by receiving a propeller wake formed by an oblique flow U, which is a combination of Ui and a circumferential flow Ue, and its forward direction component is generated as a thrust force T.

By the way, in the past, since the wing body consisting of the rudder plate c and the rudder horn d was expanded only in the depth direction of the ship, there was a large Regarding the oblique flow U that has a circumferential velocity component, it is possible to generate an effective lift force L and, by extension, a thrust force T, but on the other hand, it has a large circumferential velocity component in the depth (vertical) direction of the ship parallel to the wing surface e. As for mixed flow, it was not possible to receive this, and it was not possible to fully utilize the energy in the wake of the propeller.

On the side and above the propeller boss on the distal side of the screw propeller 2, a wing body 8, which is a feature of the present invention, is provided. In this embodiment, as shown in FIGS. 4, 5, and 6, the wing body 8 is formed integrally with the gudgeon portion 6, is relatively long in the longitudinal direction, and has a screw. Provided at the drooping end 4a of the rudder horn 4, which is located away from the center of rotation of the propeller 2 and facing a position (upper in the figure) where a propeller wake with a particularly large circumferential velocity component (high turning energy) is generated. It will be done. Although the wing body 8 is formed in the shape of a wing along the ship's ship direction like the rudder plate 5, it is largely expanded horizontally in the width direction of the ship. This wing body 8 receives a propeller wake having a large circumferential speed component in the depth (vertical) direction of the ship perpendicular to the wing surface, and lift force L
, and its forward direction component is configured to be generated as thrust T.
次に、作用について述べる。 Next, we will discuss the effect.

その省燃費、即ち省エネルギ化を達成できる。 When the ship is propelled, the screw propeller 2 is rotated to generate a propeller wake, and this propeller wake is pushed toward the rear of the ship, thereby causing the ship to move forward. At this time, the fourth
5 and 6, the blade body 8 of the present invention is capable of absorbing the axial flow Ux and the circumferential flow Ue generated by the rotation of the screw propeller 2, especially the rudder plate 5.
Lift is generated by receiving the diagonal flow U which is combined with the circumferential flow Ue directed toward the depth (vertical) direction of the ship, which could not be received by the ship, and the thrust force T as the forward direction component
can be generated and added to the propulsion of these hulls together with the thrust obtained by the rudder plate 5, thereby achieving fuel saving, that is, energy saving.

でき、常に安定した性能を発揮する。 In addition, as shown in FIG. 6, since the wing body 8 is provided on the rudder horn 4 fixed upstream of the rudder plate 5, the rudder plate 5 turns around the gudgeons 6 and 7 when the ship turns. There is no mutual displacement with the screw propeller 2 even if the propeller is rotated, and the thrust force T can be generated by capturing the propeller wake before it is disturbed by the rudder plate 5, so that stable performance is always exhibited.
