Description
Technical field
Technical field of ships is the utility model is related to, especially relates to a kind of Fishtail rudder.
Background technology
The maneuverability of ship is one of important performance of ship, it is related to the shipping safety of ship.Except ship of spraying water
Or the special ship of equipment is operated using rudder paddle etc., the maneuverability of general ship is mainly to be realized by rudder.The form of rudder
Have very much.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 vast market prospect.
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
To solve the above-mentioned problems, the utility model proposes a kind of Fishtail rudder, including front end, middle body and fish tail, front end
Managed for rudder is first, smoothly transit and be connected with middle body；Middle body is streamlined NACA sections, its both sides includes plate by rudder；Fish tail includes
The plane stern transom plate of the trailing edge plate, the clapboard of both sides and the afterbody that are connected with the middle body.
Further, Fishtail rudder further 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 utility model 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, not only can be in order to welding, but also can realize rudder front and the light of body in rudder
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 utility model.
Fig. 2 is the utility model stem profile.
Fig. 3 is the utility model afterbody profile.
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
Specific embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, which is merely to illustrate
The utility model rather than limitation the scope of the utility model, various of equal value shapes of the those skilled in the art to the utility model
The modification of formula falls within the application appended claims limited range.
The utility model 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
The first pipe of rudder, 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 transits and connects；Middle body 2 is streamlined NACA sections, is made of plate 21 by the rudder of both sides.The section is by vertical
In the rudder blade section that the plane of rudder stock axis intercepts, the shape of section uses NACA forms, and NACA is a kind of most common streamline
Type profile, using NACA sections, builds simply, easy for construction, hydrodynamic performance is good.Wherein, middle body 2 further includes some for adding
Strong vertical partition plate 6 and horizontal baffle 5, horizontal baffle 5 and vertical partition plate 6 play the role of strengthening rudder blade structure.Each two is hung down
There is a horizontal baffle between straight baffle, the section of middle body 2 is divided for 3~8 pieces by vertical partition plate 6,6 and one side rudder of vertical partition plate
Other plate 21 is connected to be commonly welded to connect with plate 21 by another side rudder by plug welding mode.The shape of vertical partition plate for rectangle or
It is trapezoidal.There is horizontal baffle 5 between each two vertical partition plate 6, horizontal baffle 5 is commonly to be welded to connect with plate 21 by a side rudder,
It is connected with plate 21 by another side rudder by plug welding mode.The shape of horizontal baffle is the shape of the section of middle body 2.According to level
The shapes and sizes of partition plate 5, are provided with the discharge orifice 7 that size and dimension is adapted on 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, not only can be in order to welding, but also can realize that rudder front smoothly transits with body in rudder.
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 3 stern transom plate 32 of fish tail is b, the water of 3 clapboard 31 of fish tail
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 utility model can increase the fairshaped camber of body and velocity circulation in section, so as to increase rudder
Lift, improves 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 utility model, still, the utility model and unlimited are described in detail above in association with attached drawing
Detail in the above embodiment, can be to the skill of the utility model in the range of the technology design of the utility model
Art scheme carries out a variety of simple variants, these simple variants belong to the scope of protection of the utility model.
