Abstract
A high-speed boat with an axe-shaped bow and a diving body comprises the axe-shaped bow. The lower portion of a stem of the axe-shaped bow is provided with the diving body which is positioned below a water line and is close to the position of a keel. Accordingly, when the boat sails in waves, vertical motion damping of the boat is increased and wave interference resistance of the bow is relatively reduced by the aid of the diving body, and vertical motion response of the boat in the waves is remarkably reduced. In addition, the size and the mounting position of the diving body are reasonably designed, accordingly, a wave absorbing effect can be realized, and wave-making resistance of the boat during sailing is reduced.
Description
[technical field]
The present invention relates to a kind of ship type, relate in particular to a kind of ship type of high-speed boat.
[background technology]
When high-speed boat navigates by water in wave, can produce significantly and jolt.For reduce wave to the exciting force of ship, increase the damping of ship when the Motion Waves, it is a kind of good measure under water that partial drainage volume is shifted to, axe bow ship type is unlike conventional ship, the above flare volume of stem waterline is larger, and underwater is sharp thin gradually, its bow has same waterline width up and down at waterline, and this has made partial drainage volume move down; Near waterline lower keel, diving body is installed again, the proportion of volume under water is further strengthened, thereby significantly reduce the motion response of ship in wave.If the profile of diving body and position design are suitable, can also produce favourable wave making and disturb, reduce wave making resistance, during erect image is many, that low powered adds bulbous bow role is such.
[summary of the invention]
Based on this, be necessary to provide a kind of ship type that can significantly reduce the motion response of high-speed boat in wave.
A ship type for high-speed boat, comprises axe shape bow, and the position that the stem bottom of described axe shape bow is positioned near keel is provided with a diving body.
In a preferred embodiment, the cross-sectional plane of described diving body is circular or oval, and the vertical section of diving body is stream line pattern, and the axis of described diving body is parallel with hull line of centers.
In a preferred embodiment, the depth of immersion of described diving body is identical with keel or be a bit larger tham keel depth of immersion; The front end of described diving body and described stem be 1.0-1.5m before the distance of horizontal surface is stem.
In a preferred embodiment, the length of described diving body is 5 meters, and the maximum cross section of described diving body is at 1/4th places of its overall length, and the major axis of the cross-sectional plane ellipse at this place is grown 1.040 meters, long 0.872 meter of minor axis; Long 1.024 meters of the major axis of the middle cross-sectional plane ellipse of described diving body, long 0.859 meter of minor axis; Long 0.832 meter of the major axis of rear 1/4th cross-sectional plane ellipses of described diving body, long 0.698 meter of minor axis.
In a preferred embodiment, the ship type of described high-speed boat has following parameter:
In a preferred embodiment, length Fu of the ship type of described high-speed boat you be less than 1.0 by moral number.
The stem bottom that above-mentioned diving body is arranged on axe shape bow is positioned at close keel position under waterline, and when ship navigates by water in wave, diving body can reduce the longitudinal motion response of ship in wave; And can reduce running resistance.
[accompanying drawing explanation]
By the more specifically explanation of the preferred embodiments of the present invention shown in accompanying drawing, above-mentioned and other object of the present invention, that Characteristics and advantages will become will be more clear.In whole accompanying drawings, identical Reference numeral is indicated identical part, and does not deliberately press actual size equal proportion convergent-divergent and draw accompanying drawing, focuses on illustrating purport of the present invention.

[specific embodiment]
For above-mentioned purpose of the present invention, feature and advantage can be become apparent more, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.A lot of details have been set forth in the following description so that fully understand the present invention.But the present invention can implement to be much different from alternate manner described here, and those skilled in the art can do similar improvement without prejudice to intension of the present invention in the situation that, so the present invention is not subject to the restriction of following public concrete enforcement.
Refer to Fig. 1, the ship type 100 of the high-speed boat of an embodiment, comprises axe shape bow 10.Stem 11 bottoms of axe shape bow 10 are positioned under waterline, near keel position, a diving body 20 are installed.
The ship type of the high-speed boat 100 of the present embodiment has following parameter:
Refer to Fig. 2, Fig. 3 and Fig. 4, diving body 20 vertical sections are stream line pattern.The cross-sectional plane of diving body 20 is circular or oval.The axis 21 of diving body 20 is parallel with hull line of centers.
The depth of immersion hf of diving body 20 is defined as diving body 20 central axis to the distance of the water surface, and it is equal to or slightly greater than keel depth of immersion, and keel line is apart from the distance of the water surface.
The leading section of diving body 20 and stem 11 are in the distance D of horizontal surface
ffor 1.0-1.5m.
Refer to Fig. 5, be depicted as front elevation and corresponding front 1/4th cross sectional drawings, middle cross-sectional plane face and rear 1/4th cross sectional drawings thereof of diving body 20.The maximum cross section of diving body 20 is at 1/4th places of its overall length.
As shown in Figure 5, the length of diving body 20 is 5 meters; Long 1.040 meters of the major axis of front 1/4th vertical section ellipses of diving body 20, long 0.872 meter of minor axis; Long 1.024 meters of the major axis of half vertical section ellipse of diving body 20, long 0.859 meter of minor axis; Long 0.832 meter of the major axis of rear 1/4th vertical section ellipses of diving body 20, long 0.698 meter of minor axis.
Above-mentioned diving body 20 is applicable to high-speed boat, is especially applicable to your moral number (F of length Fu
n) be less than 1.0 high-speed boat.
Stem 1 bottom that the diving body 20 of the present embodiment is arranged on axe shape bow 10 is positioned at close keel position under waterline, and in motion, diving body 20 can reduce the longitudinal motion response of ship in wave to ship.When the yardstick of diving body and installation site are when suitable, diving body 20 can also form favourable wave making and disturb, and plays the effect that reduces wave making resistance.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
