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] like figure 1and 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] like 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 overh...

Abstract

A monolithic semi-planing wave piercing ship in the field of small speedboats, including: an improved hybrid inward-inclining wave-piercing bow, a semi-planing main hull below the waterline, an inward-inclining wave-suppressing freeboard and a fully enclosed superstructure; the improved Type hybrid inclination wave piercing bow includes: stem, fully enclosed bow deck and bow freeboard, bow freeboard includes: inclination part and outward inclination part, wherein: inward inclination part and outward inclination part meet to form freeboard knuckle line, The angle γ between the projection of the freeboard knuckle line on the mid-longitudinal section and the waterline is to be 1°~3°. The invention improves the wave penetration, stealth, rapidity, wave making, stability and loading capacity of the hull, further controls the wetness of the freeboard compared with the prior art, and uses the freeboard to provide lift to lift the hull, reducing resistance.

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...
