Advantage of the invention is that：
1, tail fin shape rudder blade meets bionics principle, can form more preferably flow field, effectively reduces the resistance of rudder generation, reaches
To the purpose for saving energy.
2, flow guide bar can bear complicated tail flow field after propeller, reduce impact of the turbulent flow to rudder blade, and then reduce resistance
Power and noise are finally reached energy saving and noise reduction purpose.
3, the elastic surface coating on rudder blade surface effectively reduces the sound of water impact, achievees the purpose that noise reduction, while can
Certain vacuole is born, internal metal part is protected.
4, the convex sword on rudder stock can effectively reduce water plant and the winding of other foreign matters.
Description of the drawings
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is A-A cross-sectional views；
Fig. 3 is rudder stock cross-sectional view.
Specific implementation mode
It illustrates below in conjunction with the accompanying drawings and the present invention is described in more detail：
In conjunction with Fig. 1-3, a kind of antiwind rudder blade of energy-saving and noise-reducing of the present invention is arranged by propeller 5, including：Rudder blade 1 is led
Flow item 2, rudder stock 3, convex sword 4.
Rudder blade 1 is designed as fish tail fin according to bionics principle, and caudal-fin models meet parabolic equation, by center line pair
Claim, be minimum value using rudder blade center line as the horizontal axis of coordinate system, at ordinate 0, is maximum value at ± L.Tail fin and upper and lower end face
It smoothly transits.
2 horizontal homogeneous of diversion pipe is distributed in rudder blade surface, and flow guide bar width is 0.02L, and height of projection is 0.05 meter, respectively
Be distributed in ± 0.15L, ± 0.3L, ± 0.45L, at ± 0.6L, at ± 0.75L, ± 0.9L, every flow guide bar head and the tail both ends and rudder
It is seamlessly transitted between limb edge.
1 surface of rudder blade is covered with elastic material coating, and coating layer thickness at least 0.02m, it is big that elastic material should meet tensile strength
In equal to 2MPa, elongation at break is more than or equal to 150%.
Convex sword 4 is circumferentially distributed on rudderpost 3,4 length of convex sword is more than or equal to the length of rudder stock 3 in water, and 4 height of convex sword is
0.1D。
As shown in Figure 1, fish caudal-fin models are presented in rudder blade 1, meet parabolic equation, be more suitable for moving under water, tail fin
Shape rudder blade 1 is unfavorable for the formation of Karman vortex street, reduces its destruction to rudder blade.Meanwhile entire 1 surface of rudder blade is covered with elasticity
Material coating, in the case that coating layer thickness is enough, noise caused by water impact and vibration reduce, and achieve the purpose that noise reduction, and
The tensile strength and elongation at break of material ensure that 1 surface of rudder blade has certain toughness, are gone back while enhancing anti-vacuole ability
Internal metallic material can be protected.
As shown in Fig. 2, 2 horizontal homogeneous of flow guide bar is distributed in rudder blade surface, flow guide bar width is 0.02L, and height of projection is
It 0.05 meter, is seamlessly transitted between every flow guide bar head and the tail both ends and rudder blade edge.Complicated wake flow passes through rudder blade 1 after propeller, by
Flow guide bar 2 guides turbulent flow, forms uniform flow field, and Reynolds number reduces, and the resistance on rudder blade surface reduces, meanwhile, it is rapid
The impact to rudder blade is flowed to reduce.
As shown in figure 3, the circumferentially distributed convex sword 4 of rudder stock 3,4 length of convex sword is more than or equal to the length of rudder stock 3 in water, convex sword
Height is 0.1D.Since rudder stock 3 and 1 junction of rudder blade and rudder stock 3 itself easily wind the sundries such as water plant, the present invention is in rudderpost 3
Upper to increase convex sword 4, once water plant winding is to a certain extent, blade 4 gives water plant larger pressure, and water plant is caused to be broken, and is detached from rudder
Axis, it is antiwind to achieve the purpose that.
