Below with reference to Fig. 1 to 4, introduce according to the embodiment of the present invention of claim 1 and 2 in detail.The bottom 2 and the current that in Fig. 1 to Fig. 4, have represented whole ship 1, ship form path 3.Current form path 3 be formed at hull bottom in the heart and towards stern 4, be the path that has gentle slope 5 in bow side, has inverted U-shaped cross section towards stern 4 sides.
Use the ship forming like this, propelling unit 6 rotate to form the current that form path 3 inside at current, and these current can advance ship 1.Much less,, when propelling unit 6 contrarotation, ship 1 can retreat.
When the active side 8a of rudder 8 left during (anticlockwise direction) rotation predetermined angular, forms the front surface of the flow impact rudder 8 of path 3 inside, stern 4 anticlockwise directions motions, thereby ship 1 left-handed turning when ship 1 advances at current.
When rudder 8 clockwise direction rotation, ship 1 right-hand turning, contrary to the above.
Therefore, the propelling unit 6 of ship 1 (forms in path 3) rotation in finite space at current, and receives antagonistic force from the water in this finite space, to travel forward.The thrust of propelling unit 6 effectively passes to current and forms the water in path 3, and becomes the larger propulsive force that will pass to ship 1.And the opening 3a of the water in current form the insulating space in path 3 as jet and from stern 4 discharges, the thrust of this jet also acts on ship 1.
Because rudder 8 forms forward, therefore at current, form the flow impact rudder 8 of path 3 inside, and flow to stern 4 sides by the space of the opposite direction through with rudder 8, thereby rotational force further increases due to these current.On the contrary, for towards after ordinary rudder, the water resistance only acting on rudder contributes to rotational force, so radius of rotation inevitably increases.
The second embodiment
The second embodiment is corresponding to claim 3.As shown in Figure 5, current form path 3 the import 3b in bow 1a side, and this import 3b is applicable to relatively little ship effectively.
The 3rd embodiment
The 3rd embodiment is corresponding to claim 4.As shown in Figure 6, current form path 3, propelling unit 6 and rudder 8 and are formed in hull bottom 2 and in the position being mutually symmetrical, and this can be used in relatively little ship.
The 4th embodiment
