Semi-small waterplane area catamaran

Abstract

The invention relates to the technical field of ships, and discloses a half-small waterplane area catamaran which comprises two sheet bodies connected through a connecting bridge, each sheet body comprises a submerged body and a slipway which are oppositely arranged, and each submerged body is connected with the corresponding slipway through a stand column. The sheet body is sequentially provided with a square tail part, a square tail transition half-small waterline face part and a small waterline face part in the length direction of the sheet body, the length of the square tail part is L1, the length of the square tail transition half-small waterline face part is L2, the length of the small waterline face part is L3, and L1: L2: L3 is 1: 1.4: 1.2-1: 1.8: 1.6. According to the catamaran, the sheet bodies of the catamaran are sequentially arranged to be the square tail part, the square tail transition half-small waterplane middle part and the small waterplane head part in the length direction of the catamaran, so that a small waterplane ship form technology with excellent seaworthiness is integrated on the basis of a conventional high-speed ship form, the motion response amplitude of the catamaran is reduced, and the stability of the catamaran is improved. And the seaworthiness and comfort of the ship form are improved. Meanwhile, the square tail design can increase the wetting area of the tail sealing plate, and the resistance performance is improved.

Description

technical field [0001] The invention relates to the technical field of ships, more specifically, to a semi-small waterplane area catamaran. Background technique [0002] Most of the existing small and medium-sized high-speed ships adopt round bilge or knuckle-shaped ship technology. This ship type technology has good fast performance and can meet the requirements of minimum propulsion power and fuel consumption. However, the seakeeping performance of the ship type is poor, especially the catamaran type. The rolling and pitching periods are close, and the ship is prone to harmonic rolling, and the seasickness rate of the occupants is high under high sea conditions, which not only seriously affects the comfort of the occupants, but also affects the efficiency of ship boarding operations. [0003] On the other hand, due to the smaller waterplane area and larger underwater submerged body, the small waterplane ship type has a strong ability to resist ship motion under high sea co...

AI Technical Summary

Problems solved by technology

[0004] In order to overcome the deficiencies in the prior art, the present invention provides a semi-small waterplane catamaran hull, which simultaneously overcomes the problems of insufficient seakeeping performance of conventional high-speed ships, poor resistance performance of small waterplane hulls, and difficult layout of hull cabins
