Problems solved by technology

When the conventional planing boat slides, only part of the bottom of the boat is in contact with the water, and the resistance is significantly reduced. However, the impact force in the waves is relatively large, and the sea area is greatly restricted.
[0003] Although conventional planing boats are relatively mature in technology, easy to manufacture, and low in construction cost, due to the influence of stability and splashing, the "dolphin phenomenon" occurred earlier in conventional planing boats, which limited their upper limit of speed
On the other hand, conventional planing boats have poor seakeeping, and their application is greatly affected by wind and waves. They have poor application capabilities in multiple sea conditions, and have a serious impact on personnel and equipment.

Embodiment Construction

[0025] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0026] combine Figures 1 to 7 , the trimaran planing boat consists of a main hull 1, two auxiliary fins 2 of the same size and a longitudinal variable curvature channel 3 connecting the main hull 1 and the auxiliary fins 2, the aspect ratio of the main hull 1 is greater than or equal to 4; the entire auxiliary The cross section of the sheet body 2 is an inverted triangle or trapezoid, the inner side 4 and the outer side 5 are inclined surfaces, and knuckles can also be set, the auxiliary sheet body 2 extends from the bow of the main hull, and the bottom line 6 of the sheet body is S-shaped, from the bow of the sheet body to the bow. The vertical distance between the stern of the hull and the keel line 7 gradually decreases, and the two auxiliary hulls account for 5%-20% of the displacement of the entire hull at rest; the main hull 1 and the auxiliary hull 2 ​​are...

Abstract

The invention provides a tri-body skimming boat, composed of a main boat body and two supplementary plate bodies in the same size. The supplementary plate body is symmetrically connected at the two sides of the boat body through a longitudinal curvature variable channel from the position 10-25% of boat length away from the bow, and the main boat body is provided with an air bleeding slot adjacent to the longitudinal curvature variable channel. The tri-body skimming boat of the invention is characterized in that only one main boat body is arranged at the bow, the supplementary plate is connected with the main boat body through the longitudinal curvature variable channel from the position close to the bow, and the tri-body skimming boat is in high-speed type. The invention can be widely applied to inland rivers, lakes, coastal areas and severe sea condition and sea area where a conventional boat can not navigate and has a broad application prospect.

Description

technical field [0001] The invention relates to a ship structure, in particular to a three-body planing boat used in inland rivers, lakes and coastal areas. Background technique [0002] Conventional planing boats are the earliest researched boats relying on hydrodynamic navigation. Many navies maintain a considerable number of planing boats. Civilian planing boats are widely used and are one of the most widely used high-performance ships. When the conventional planing boat slides, only part of the bottom of the boat is in contact with the water, and the resistance is significantly reduced. However, the impact force in the waves is relatively large, and the sea area is greatly restricted. [0003] Although conventional planing boats are relatively mature in technology, easy to manufacture, and low in construction cost, due to the influence of stability and splashing, the "dolphin phenomenon" occurred earlier in conventional planing boats, which limited their upper speed limi...
