Abstract
The present invention provides a kind of Fishtail rudder, including front end, middle body and fish tail.Front end is the first pipe of rudder, smoothly transits and is connected with middle body；Middle body is streamlined NACA sections, and its both sides includes plate by rudder；Fish tail includes trailing edge plate, the clapboard of both sides and the plane stern transom plate of afterbody being connected with middle body.Wherein Fishtail rudder also includes some vertical partition plates and horizontal baffle for being used to strengthen, and has a horizontal baffle between each two vertical partition plate, discharge orifice is furnished with above horizontal baffle.Fishtail rudder is divided into some pieces by vertical partition plate, and Fishtail rudder is symmetrical.
Description
Technical field
The present invention relates to technical field of ships, especially relates to a kind of Fishtail rudder.
Background technology
The maneuverability of ship is one of important performance of ship, and it is related to the shipping safety of ship.Except ship of spraying water
Or the special ship using the operation equipment such as rudder oar, the maneuverability of general ship are mainly to be realized by rudder.The form of rudder
Have a lot.The maneuvering performance of flap-type rudder is relatively good, but needs more complicated operating mechanism, and economy is poor.So exploitation
Go out all good rudder blade profile type of a kind of maneuverability and economy to have great importance and wide market prospects.
Patent application (CN102390516 A) is related to a kind of Fishtail rudder body, but the fish tail of the patent application and middle body are straight
Connect connected, the curve transition of plate is complex by rudder, higher to construction requirement.
The content of the invention
In order to solve the above problems, the present invention proposes a kind of Fishtail rudder, including front end, and middle body and fish tail, front end is rudder
Head pipes, smoothly transit and are connected with middle body；Middle body is streamlined NACA sections, and its both sides includes plate by rudder；Fish tail includes and institute
State trailing edge plate, the clapboard of both sides and the plane stern transom plate of afterbody of middle body connection.
Further, Fishtail rudder also includes some vertical partition plates and horizontal baffle for being used to strengthen.
Further, there is a horizontal baffle between each two vertical partition plate.
Further, discharge orifice is furnished with above horizontal baffle.
Further, Fishtail rudder is divided into some pieces by vertical partition plate.Moreover, Fishtail rudder is symmetrical.
The present invention has the advantage that：
Fish tail can increase the fairshaped camber of body and velocity circulation in section, so as to increase the lift of rudder, improve steerage.
Front end carries out transition using rudder head pipes, both can realize rudder front and the light of body in rudder again in order to weld
Slip over and cross.
Fish tail is connected by trailing edge plate with body in rudder, very convenient construction and ensure that the intensity of structure.
Brief description of the drawings
Fig. 1 is the profile of the present invention.
Fig. 2 is stem profile of the present invention.
Fig. 3 is afterbody profile of the present invention.
Front end 1, rudder head pipes 11, middle body 2, fish tail 3, clapboard 31, stern transom plate 32, trailing edge plate 4, horizontal baffle 5, vertically every
Plate 6, discharge orifice 7.
Embodiment
The embodiment of the present invention is described in detail below in conjunction with the accompanying drawings, the embodiment is merely to illustrate this hair
Bright rather than limitation the scope of the present invention, modification of the those skilled in the art to the various equivalent form of values of the present invention fall within this
Apply for appended claims limited range.
The present invention provides a kind of symmetrical Fishtail rudder, such as Fig. 1, including front end 1, middle body 2 and fish tail 3.Front end is that rudder is first
Pipe, the first pipe of rudder are in front of rudder, connect plate by two rudder blades and the tubular structure of booster action is played to structure, with middle body
Smoothly transit and connect；Middle body 2 is streamlined NACA sections, is made up of plate 21 by the rudder of both sides.The section is by perpendicular to rudder
The rudder blade section that the plane of rod axis intercepts, the profile of section use NACA forms, and NACA is the most frequently used a kind of streamlined cuts open
Face, using NACA sections, build simply, easy for construction, hydrodynamic performance is good.Wherein, middle body 2 is also used for what is strengthened including some
Vertical partition plate 6 and horizontal baffle 5, horizontal baffle 5 and vertical partition plate 6 play a part of strengthening rudder blade structure.Each two vertically every
There is a horizontal baffle between plate, the section of middle body 2 is divided for 3~8 pieces by vertical partition plate 6, plate by the side rudder of vertical partition plate 6 and one
21 is commonly are welded to connect, and are connected with plate 21 by another side rudder by plug welding mode.Vertical partition plate is shaped as rectangle or trapezoidal.
Have horizontal baffle 5 between each two vertical partition plate 6, horizontal baffle 5 with plate 21 by a side rudder to be commonly welded to connect, it is and another
Plate 21 is connected by plug welding mode by side rudder.The shape of horizontal baffle is the shape of the section of middle body 2.According to horizontal baffle 5
Shapes and sizes, the adaptable discharge orifice 7 of size and dimension is provided with horizontal baffle 5.
Such as Fig. 2, front end 1 includes rudder head pipes 11, and rudder head pipes 11 are connected by welding manner with middle body 2.Front end uses rudder
First pipe carries out transition, both again can realize that rudder front smoothly transitted with body in rudder in order to weld.
As shown in figure 3, fish tail 3 includes the plane stern transom plate 32 of two clapboards 31 and an afterbody positioned at both sides.Fish
Tail 3 is by trailing edge plate 4 with middle body 2 by being welded to connect.If the width of the stern transom plate 32 of fish tail 3 is b, the water of the clapboard 31 of fish tail 3
Flat length is c, and the overall length of the section of rudder is L, then b/L=0.06~0.09, c/L=0.05~0.07.
The Fishtail rudder of the present invention can increase the fairshaped camber of body and velocity circulation in section, so as to increase the liter of rudder
Power, improve steerage.Fish tail is connected by trailing edge plate with body in rudder, very convenient construction and ensure that the intensity of structure.
The preferred embodiment of the present invention is described in detail above in association with accompanying drawing, still, the present invention is not limited to above-mentioned reality
The detail in mode is applied, in the range of the technology design of the present invention, a variety of letters can be carried out to technical scheme
Monotropic type, these simple variants belong to protection scope of the present invention.
