Abstract
The utility model discloses a deep V-profile high-speed work boat stern structure, which comprises a boat body (1) with a V profile. The stern structure is characterized in that: the bottom of the tail of the boat body (1) is provided with a cambered surface (2) which is raised upwardly, the starting point A of the cambered surface (2) is positioned on the tail of the boat body (1), the end point B of the cambered surface (2) is positioned on the boat body (1), the distance range between B and A is from one twentieth of the boat length L to one eighth of the boat length L, and the radius of curvature of the cambered surface (2) is one to two times larger than the boat length L. The stern structure is simple, the design is ingenious, the wave-making resistance generated by the stern structure is low, the boat body still can be kept in good parallel with the water surface as a deep V-profile high-speed boat travels at high speed, and thereby the stability of the boat is good, and the produced wave making resistance is small.
Description
Technical field
The utility model relates to a kind of stern construction to be improved, especially a kind of at dark V profile high speed operation ship, can improve the stability of this kind boats and ships when navigating by water at a high speed, reduces the stern construction of the suffered wave making resistance of hull.
Background technology
Dark V profile boats and ships are a kind of high-speed ships, when navigating by water at a high speed on the water surface, are in the state of kinematic motion that a kind of half draining is partly slided, and this state is the boats and ships of navigation down, have both possessed certain high speed of a ship or plane, and bigger loading nargin is arranged again; But exist some problems too, wherein the most important is exactly when the speed of a ship or plane of boats and ships is higher, and foremost part of ship can stressed raising up, and this just makes the less stable of boats and ships, and the wave making resistance that boats and ships produce under this state is also bigger.Therefore need a kind ofly can address the above problem now, make dark V profile boats and ships under the high speed operational configuration, keep hull level, the way of less wave making resistance or structure as far as possible.
Summary of the invention
The utility model is in order to solve the above-mentioned deficiency of existing in prior technology, propose a kind of simple in structure, design ingenious, can allow dark V profile boats and ships under the high speed operational configuration, still can allow the hull and the water surface keep good parallelism, thereby make the good stability of boats and ships, the dark V profile high speed operation ship stern construction that the wave making resistance that is produced is little.
Concrete solution of the present utility model is: a kind of dark V profile high speed operation ship stern construction, comprise that section is a vee-type hull 1, it is characterized in that: the tail end bottom of described hull 1 is provided with the cambered surface 2 to upper process, the starting point A of cambered surface 2 is positioned at the tail end of hull 1, the terminal point B of cambered surface 2 is positioned on the hull 1, and the distance range between B and the A is
Captain L extremely
Captain L, the radius of curvature of cambered surface 2 are 1 to 2 times of captain L.
The utility model is compared with prior art, has following advantage:
The dark V profile high speed operation ship of this kind of form stern construction, it is simple in structure, design ingenious, rationally distributed, on the quarter the cambered surface that is provided with of end can allow the boats and ships afterbody that is in the high speed operational configuration under produce a lift that makes progress, and this lift can make the stem sinking of boats and ships, makes hull and the horizontal surface keeping parallelism of trying one's best, the stability of shipping high speed navigation can either be guaranteed like this, the wave making resistance that boats and ships produce can also be reduced.Therefore we can say that the dark V profile high speed operation gear of this kind structure is equipped with multiple advantage, be suitable in shipbuilding, carrier, applying that its market outlook are comparatively wide.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the enlarged drawing of the stern part of the utility model embodiment.
The specific embodiment
Below in conjunction with the description of drawings specific embodiment of the present utility model.As shown in Figure 1 and Figure 2: a kind of dark V profile high speed operation ship stern construction, comprise that section is a vee-type hull 1, be provided with cambered surface 2 to upper process in the tail end bottom of hull 1, the starting point of cambered surface 2 is A, is positioned at the tail end of hull 1; The terminal point of cambered surface 2 is B, is positioned at the bottom of hull 1, and the distance range between B and the A is
L extremely
L(L is a hull length), and the radius of curvature of cambered surface 2 is 1L to 2L.
The hull 1 that is provided with cambered surface 2 is carrying out high speed when navigating by water, because the existence of cambered surface 2, the afterbody of hull 1 can produce the power of a rising, this power can press down fore, the time boats and ships and horizontal surface the angle of inclination diminish, make boats and ships and water surface keeping parallelism state as far as possible, stability when having improved ship's navigation, simultaneously stem also can remain and the contacting of the water surface, and helps reducing wave making resistance, has improved the overall performance of ship's navigation.
Claims (1)
