Fig. 1 is the block diagram that illustrates according to the boats and ships of an embodiment of the invention.Fig. 2 illustrates the stern of boats and ships shown in Figure 1 and the amplification stereogram of stern construction.

As depicted in figs. 1 and 2, boats and ships 100 have stern 110 and stern construction 120.

Stern 110 has propulsion unit 112 and rudder 114.Stern 110 is positioned at below the sea level when boats and ships 100 navigation, advances this boats and ships 100, and the control rotary current.In embodiments of the present invention, propulsion unit 112 can utilize propelling unit to implement.When boats and ships 100 navigation, propulsion unit 112 edges and the direction promotion seawater of the navigation opposite direction of boats and ships and the propulsive force of generation edge navigation direction.When producing propulsive force, because the rotation of propulsion unit 112 produces along the vortex rotary current of the hand of rotation of propulsion unit 112.This rotary current has unsymmetric structure based on the central axis of propulsion unit 112 in top, bottom, port side and starboard side, so that rotary current can cause a large amount of degradations of energy.

Stern construction 120 comprises a plurality of stern attachments 121,122,123,124 and cause the variation of the rotary current that is produced by propulsion unit 112, reduces thus the amount of the degradation of energy of generation when boats and ships 100 navigation.In one embodiment, can change spin intensity and flow velocity by these a plurality of stern attachments 121 to 124, change thus the flow velocity that enters stream and fluid inlet angle to propulsion unit 11, the amount of the degradation of energy that occurs when being reduced in ship's navigation thus.

In order to weaken the rotating energy of the seawater that is produced by rotary current, at least a portion in a plurality of stern attachments 121 to 124 but non-ly all have different length and be attached at the diverse location place.At this and since rotary current usually on the quarter the position around 110 produces along non-homogeneous direction with inhomogeneous size, therefore, the length of stern attachment 121 to 124 and attachment location can be considered on the quarter the rotary currents of generations around 110 and determine.

In yet another embodiment of the present invention, stern attachment 121 to 124 can be constructed with identical or different length.

In addition, in this embodiment, each in a plurality of stern attachments 121 to 124 all is constructed with at least a structure in torsion structure and the unsymmetrical section structure, and described torsion structure reverses based on different rotation axiss.When rotary current flowed along torsion structure or unsymmetrical section structure, the above-mentioned structure of corresponding stern attachment can weaken or offset this rotary current, so that the direction of rotary current can be changed into the initial flow direction of seawater, reduces thus the amount of degradation of energy.

In one embodiment, a plurality of stern attachments 121 to 124 can have different length and can be attached at the diverse location place, and the torsion structure that can be constructed with the unsymmetrical section structure and reverse based on the different rotary axis.

Fig. 3 is the view of stern construction shown in Figure 2.

As shown in Figure 3, a plurality of stern attachments 121 to 124 are configured to have the torsion structure that reverses based on the different rotary axis.The above-mentioned torsion structure of stern attachment is determined according to the size and Orientation of the rotary current that on the quarter produces in 110, in order to weaken or offset this rotary current.

In one embodiment, stern attachment 121 to 124 can be constructed with based on the size of rotary current and the corresponding torsion structure that reverses.In other words, some stern attachments that are attached at the position that produces large rotary current can further be reversed, and some stern attachments that are attached at the position that produces little rotary current can less be reversed.

Although for schematic purpose has been described preferred implementation of the present invention, but it will be understood by those skilled in the art that in the situation of disclosed scope and spirit of the present invention in not departing from by claims and can make various modifications, interpolation and replacement.
