Description
Technical field
The present invention relates to pushing away ship body characterized by low resistance using three bow sides of super U-shaped waterline, belong to field of ocean engineering.
Background technology
With the lasting aggravation of global greenhouse effect, green, low energy consumption ship, the particularly exploitation of ocean engineering class ship
Design increasingly causes the concern of industry.Ocean engineering class ship, such as wind turbine installation vessel etc., because the engineering of itself is special
Property, need that there is suitable deck effective area and reliable stationkeeping ability.Therefore, such ship generally parallel (middle) body is longer,
Become a mandarin all very short shallow draft full formed ship oceangoing ship of section, run.Larger Block Coefficient and the too short section that becomes a mandarin lead to such ship
During oceangoing ship navigation, resistance is higher, and quick performance is poor；And more general fine ship oceangoing ship is compared, need bigger dynamic positioning energy
Power.
Content of the invention
In order to realize above-mentioned purpose, the present invention provides a kind of three bow sides using super U-shaped waterline to push away ship body characterized by low resistance.
The technical scheme that the present invention takes is as follows：
Three bow sides of super U-shaped waterline push away ship body characterized by low resistance, including hull；Hull includes stem, middle part and afterbody；Stem has
One head end is very thin and dished flat line；Shape is connected with super U-shaped waterline, main deck line curve smoothing transition by flat line
Become to have the stem of straight bow head post；The bottom of stem has several bow sides and pushes away installation pipe tunnel；Middle part is parallel (middle) body, adopts
Connect hull bottom with the circular arc turn of the bilge；Afterbody is square tail form, including rising hull bottom；Stem, middle part, afterbody carry out smooth connection structure
Become shiplines.
The quantity that bow side pushes away is three.
Stem is straight bow, and stem includes two super U-shaped drinking water Water Planes：Ballast draft Water Plane, scantling draft waterline
Face and the very thin concave flat line face of a head end, main deck line face；Flat line face transits to described ballast by curve smoothing and eats
At water waterline and at scantling draft waterline；Scantling draft Water Plane passes through to tilt flare and described main deck contours connection.
It is 0.62 ~ 0.7 that super U-shaped waterline refers to water plane coefficient；Half immersion angle is 80 ° ~ 90 °.
The very thin concave flat line face of head end, flex point captain direction position and the 3rd bow side push away home position consistent or
Slightly forward, should ensure that the 3rd bow side ejector sleeve tunnel width is not more than side and pushes away 2.5 times of diameter.
Middle part is a parallel (middle) body part.
Parallel (middle) body partial-length accounts for the 60% ~ 70% of superintendent officer.
Afterbody is a square tail.
The hull bottom wicking height of square tail and length are than for 0.2 ~ 0.25.
Beneficial effect of the present invention：It is 0.62 ~ 0.7 using water plane coefficient；Half immersion angle is 80 ° ~ 90 ° of super U-shaped waterline,
With the parallel (middle) body part accounting for hull overall length more than 60%, effectively meet middle low speed ocean engineering class ship effective to deck
While area and volume of compartment require, greatly reduce the wave making resistance being subject to during ship's navigation, improve the rapidity of ship, warp
Ji property and practicality.Stem can arrange three pipe tunnel formula sideways-acting propellers of installation, and maximum thrust loss is less than 10%, with tail
The propeller cooperation in portion, can be economical, is reliably achieved the dynamic positioning function of brilliance, improves the reliability of Engineering shipping work
Property and flexibility ratio.Ballast waterline and designed water line stem are all designed using super U-shaped waterline, can take into account ship in various running working conditions
Under economy.

Specific embodiment
The present invention will be further described below in conjunction with the accompanying drawings：
As Figure 1-3：Three bow sides of super U-shaped waterline push away ship body characterized by low resistance, and including hull 1, hull 1 includes stem 2, middle part
3 and afterbody 4.Stem 2 has that a head end is very thin and dished flat line 5.By flat line 5 and super U-shaped waterline 6, main deck
Line 7 is used curve smoothing transition to connect and is formed straight bow head post 8.Stem also has bow side and pushes away installation pipe tunnel 9, preferably 3 bows
Side pushes away form, with the thrust loss impact overcoming the beam to cause.Middle part 3 is parallel (middle) body, preferably adopts the circular arc turn of the bilge even
Connect hull bottom.Afterbody 4 includes raising hull bottom 10, to improve run flow field during navigation.By stem 2, middle part 3, afterbody 4 carries out fairing
Connect and compose hull 1 molded line.
Stem 2 is straight bow, and stem 2 includes two super U-shaped drinking water Water Planes：Ballast draft Water Plane, scantling draft water
