Abstract
The invention relates to a ship gas shell baffle energy-saving device. It discloses the requirement of bottom driving structure which can effectively form bottom thin layer air film to achieve ship gas shell baffle and improve the speed of the ship.
Description
The present invention is a Ship Energy Saving Device, relates to a kind of ship by air layers reducing resistance device.
The inventor draws on the basis of bubble chamber film constant on the flat board under water in research, and then work out hull bottom thin layer air film and form rule, designed the ship by air layers reducing resistance apparatus system, when the hull bottom input air, the effect of the deflector device by the hull bottom horizontally set forms hull bottom thin layer air film, realize ship by air layers reducing resistance, and obtained the national inventing patent (patent No.: 851019919), it is characterized by the height of hull bottom deflecting plate trailing edge opening in 1987.Deflecting plate is the main device that boats and ships are realized the thin layer air layers reducing resistance, by further research and test explanation, the air of input hull bottom will effectively form hull bottom thin layer air film, and except the requirement to deflecting plate trailing edge opening, the back shape of deflecting plate has very big influence.The deflecting plate of hypsokinesis is subjected to water currents to form the parabolical bubble easily, destroys the thin layer air film and forms, and the height between hypsokinesis deflecting plate back characteristics and the hull bottom is less than the height of trailing edge opening.On the basis of test and research, the inventor has designed rational hull bottom thin layer air film deflector device.Reasonably the smooth-going or band of deflecting plate plate face leans forward, but also arch design such as wing shape, deflecting plate leading edge curved convergent and bottom plating are fixedly connected, and the characteristics of this structure have the height greater than the trailing edge opening between the deflecting plate back side and the hull bottom of living in.
Can utilize steel plate or other materials to make deflecting plate during concrete enforcement, deflecting plate generally is installed between the skirtboard of the hull bottom left and right sides.The opening that has certain altitude between its trailing edge of deflecting plate and the hull bottom also is the flow export of air.The leading edge curved convergent of deflecting plate also is fixedly connected by welding or additive method and hull bottom.Deflecting plate lateral cross section appearance curve is made every effort to smooth-going or band leans forward, but also arch design such as wing shape, bigger water conservancy diversion backboard between the deflecting plate back side and the hull bottom of living in is tall and big in the height of deflecting plate trailing edge opening, thereby the air by deflecting plate flows out when forming hull bottom thin layer air film along the trailing edge opening, can overcome the adverse effect that current form air film because deflecting plate reasonably designs.
Further set forth concrete enforcement of the present invention below in conjunction with accompanying drawing.
As accompanying drawing, this ship by air layers reducing resistance device mainly comprises bottom plating 1, deflecting plate 2, trailing edge opening 3, its cross-sectional profile curve is smooth-going or band leans forward the deflecting plate back side 4 and leading edge 5, it is characterized by the deflecting plate back side 4 that its cross-sectional profile curve is smooth-going or band leans forward above the deflecting plate 2, leading edge 5 curved convergent and the bottom plating 1 of deflecting plate 2 are fixedly connected, when air is input between bottom plating 1 and the deflecting plate 2, flow out formation thin layer air film by the trailing edge opening 3 that forms between deflecting plate 2 and the bottom plating 1, because the deflecting plate back side 4 that its cross-sectional profile curve is smooth-going or band leans forward can overcome the adverse effect of current, guaranteed that the hull bottom air film forms the realization ship by air layers reducing resistance.
Ships that transport and high-speed ship all can be used the present invention and realize drag-reduction energy-saving and improve the speed of a ship or plane.
Claims (3)
1. ship by air layers reducing resistance device, mainly comprise bottom plating 1, deflecting plate 2, trailing edge opening 3, its cross-sectional profile curve is smooth-going or band leans forward the deflecting plate back side 4 and leading edge 5, it is characterized by the deflecting plate back side 4 that its cross-sectional profile curve is smooth-going or band leans forward above the deflecting plate 2, leading edge 5 curved convergent and the bottom plating 1 of deflecting plate 2 are fixedly connected, when air is input between hull bottom 1 and the deflecting plate 2, flow out formation thin layer air film by the trailing edge opening 3 that forms between deflecting plate 2 and the bottom plating 1, because the deflecting plate back side 4 that its cross-sectional profile curve is smooth-going or band leans forward can overcome the adverse effect of current, guaranteed that hull bottom thin layer air film forms the realization ship by air layers reducing resistance.
2. as power 1 described ship by air layers reducing resistance device, the deflecting plate back side 4 that its cross-sectional profile curve on deflecting plate 2 is smooth-going or band leans forward also can form arch wing shape when being fixedly connected with leading edge 5 curved convergent of deflecting plate 2 and with bottom plating 1, when air is input between bottom plating 1 and the deflecting plate 2, flow out formation thin layer air film by the trailing edge opening 3 that forms between deflecting plate 2 and the bottom plating 1, because its cross-sectional profile curve is smooth-going or the band deflecting plate back side of leaning forward 4 forms arch wing shapes with leading edge 5, be beneficial to the adverse effect that overcomes current and effective formation of hull bottom air film.
3. as right 1 and right 2 described ship by air layers reducing resistance devices, have the height of the height at big highly place between the deflecting plate back side 4 that its cross-sectional profile curve on deflecting plate 2 is smooth-going or band leans forward and the bottom plating 1 greater than the trailing edge opening 3 that forms between deflecting plate 2 and the bottom plating 1.
