Problems solved by technology

However, the part of the speedboat involved in this technology has relatively high navigation resistance, complex power and propulsion devices, and the discontinuity of the bow and superstructure design makes it face the attack problem brought by the rising waves when sailing through waves.
At the same time, the design of this scheme is not suitable for small speedboats.

Embodiment 1

[0044] likefigure 1 and figure 2 As shown, this embodiment includes: a semi-planing main hull 1 below the waterline, an improved hybrid inward-inclining wave-piercing bow 2, a fully enclosed superstructure 3, and an inward-inclining wave-suppressing freeboard 4.

[0045] The characteristics of the improved hybrid introverted wave-piercing bow 2 in this embodiment are: having wave-piercing and stealth characteristics; the length of the bow accounts for 0.5±0.025 of the main hull.

[0046] The improved hybrid inclination wave piercing bow includes: a stem 8 , a fully enclosed bow deck 9 and a bow freeboard 10 .

[0047] Such as image 3 and Figure 4 As shown, the described wave-pressing inward-inclining freeboard 4 adopts an inward-inclination design, and its inclination angle, that is, the acute angle θ between the transverse section line between the deck edge and the waterline and the middle longitudinal section, takes a value from 5° to 15°. Width L of the freeboard ove...

Abstract

The invention discloses a single-body semiplaning wave-piercing ship and belongs to the field of small speed boats. The single-body semiplaning wave-piercing ship comprises an improved mixing type inward-tilting wave-piercing bow, a semiplaning underwater main ship body, an inward-tilting wave-pressing freeboard and a totally-enclosed upper building, wherein the improved mixing type inward-tilting wave-piercing bow comprises a bow column, a totally-enclosed bow deck and a tow freeboard, the tow freeboard comprises an inward-tilting part and an outward-tilting part, the inward-tilting part and the outward-tilting part are connected to form a freeboard knuckle line, and the included angle gamma between the projection, on the longitudinal section in center plane, of the freeboard knuckle line and the waterline ranges from 1 degree to 3 degrees. According to the single-body semiplaning wave-piercing ship, the wave-piercing capacity, the hiding capacity, the rapidness, the wave making capacity, the stability and the loading capacity of the ship body are improved; compared with the prior art, flooding and wetting of the freeboard are further controlled, lifting force is provided by the freeboard to lift the ship body, and resistance is reduced.

Description

technical field [0001] The invention relates to a ship shape design in the field of small speed boats, in particular to a single-body semi-planing wave piercing ship. Background technique [0002] The progress of the times and the progress of transportation depend on and promote each other. In order to complete surface activities more efficiently, the demand and research on high-performance ships are also increasing, which promotes the continuous accumulation and development of high-performance ship technology, thereby further promoting social development. Ship designers are constantly trying to integrate more good features into a single ship. Among the ships launched one after another, there are both single-body design and three-body design; there are both displacement ships and planing boats. WPV is one of these new ship types. Wave piercing ships include monohull and catamaran wave piercing ships. Compared with the catamaran wave piercing vessel, the monohull wave pie...
