Problems solved by technology

[0002] Whether it is a monohull planing boat, a hovercraft or a catamaran, they all belong to the dynamic support type ship, and the catamaran is a static floating type ship. In a specific sailing environment, they play their own advantages, but none of them can have high speed at the same time. , low power, wave elimination, good seaworthiness, high stability and good economic benefits

Embodiment Construction

[0016] Attached below Figure 1~3 Examples are also given to describe the present invention in detail.

[0017] The middle part of the M ship type of the present invention is the main hull, and the two sides are wave-absorbing hulls symmetrical to the longitudinal middle section. Such as figure 1 In the cross-section shown, there is a longitudinally connected air passage at the bottom of each wave-absorbing hull, the main hull adopts a planing boat knuckle transition to the air passage, and double breaks are set from the midship to the stern, as shown in figure 2 shown. The aspect ratio of this ship type is less than 3.33, and the opening width of the air passage gradually decreases from the bow to the midship. If the air passage is too wide, the longitudinal navigation stability is poor. The ratio between the half widths of the main hull is 1:1. The bottom of the cross-sectional shape of the main hull adopts a knuckle type, and the bottom slant angle of the midship stern...

Abstract

The invention discloses a wave-absorbing M ship type line type used in warships. The wave-absorbing M ship type line type has the advantages of being high in speed, low in power and good in seaworthiness, and absorbing waves. The middle of the M ship type line type is provided with a main ship body. The two sides of the M ship type line type are provided with wave-absorbing ship bodies symmetrical about the longitudinal middle cross section of the main ship body. The bottom of each wave-absorbing ship body is provided with an air channel penetrating in the longitudinal direction. The bow and the stern of the main ship body are in transition to the air channels by adopting skimming boat bevel line types. Double-break grades are arranged from the middle to the bow and the stern. The length-width ratio of the M ship type is smaller than 3.33, the opening width of the air channels gradually decreases in a transition mode from the ship bow to the middle of the ship, the ratio of the opening width of the portions, located on the middle of the ship, of the air channels to the half-width of the main ship body is 1:1, the angle form is adopted in the bottom of the cross section of the main ship body, and the value of the oblique ascension angle of the bottom of the stern is from 10 degrees to 15 degrees.

Description

technical field [0001] The invention relates to the technical field of ship shape design, in particular to a wave-suppressing M-shaped ship shape used for ships to realize high-speed shallow draft. Background technique [0002] Whether it is a monohull planing boat, a hovercraft or a catamaran, they all belong to the dynamic support type ship, and the catamaran is a static floating type ship. In a specific sailing environment, they play their own advantages, but none of them can have high speed at the same time. , low power, wave elimination, good seaworthiness, high stability and good economic benefits. Contents of the invention [0003] In view of this, the present invention provides a wave-absorbing M-shape line for ships, which can have the advantages of high speed, low power, wave-absorbing, and good seaworthiness. [0004] In order to solve the problems of the technologies described above, the present invention is achieved in that: [0005] The middle part of the M...
