Split type broken-stage planing boat with plurality of independent elastic planing surfaces

Abstract

The invention relates to the technical field of planing boats, in particular to a split type broken-stage planing boat with a plurality of independent elastic planing surfaces. The boat comprises a main boat body, X front sliding sub-yacht bodies are arranged below the longitudinal front portion of the mainboat body side by side, Y rear sliding sub-boat bodies are arranged below the longitudinal rear portion of the main boat body side by side, X and Y are positive integers, and X+Y is larger than or equal to 3 and smaller than or equal to 8. The X front sliding sub-hulls are distributed at equal intervals, the Y rear sliding sub-hulls are distributed at equal intervals, and intervals are formed between the tails of the X front sliding sub-hulls and the heads of the Y rear sliding sub-hulls. The sliding end face of the main boat body is arranged to be the multiple independent sub-sliding end faces which are arranged at intervals, a certain elastic buffer space is formed between each sub-sliding end face and the main boat body, and the damping structure can absorb most of vibration, so that the vibration influence of water surface waves on the main boat body during high-speed sailing is reduced.

Description

technical field [0001] The invention relates to the technical field of planing boats, in particular to a split-type step-down planing boat with multiple independent elastic sliding surfaces. Background technique [0002] There are four main types of high-speed ships: planing craft, hovercraft, hydrofoil craft, and ground effect ships. They each have their own advantages and disadvantages. Among them, the hull structure and construction process of planing boats are the simplest among high-speed ship types and are the most widely used. In particular, step-off planing boats have a higher speed in still water and better stability, but step-down planing boats also have a fatal flaw, that is, their stability in waves is very poor, which limits the practical application of step-off planing boats. the main obstacle. Whether or not the stability of the step-off planing boat can be greatly improved in waves is the key to expanding its application range. [0003] As early as 1995, E....

AI Technical Summary

Problems solved by technology

[0006] The "sea knife boat" that appeared in the 1970s used a triangular slender sliding surface. The lift of the sliding surface was mainly concentrated at the rear. Response strength in wave navigation, self-swaying frequency is reduced

When sailing, there are two supporting surfaces at the bottom of the hull, so in still water, the trim angle of the bottom surface of the hull is very stable, and the attitude of the hull is also very stable, but in waves, the attitude of the hull is difficult to maintain stability, and the seaworthiness is very poor
