Problems solved by technology

[0003] At present, high-speed planing boats are generally three-body planing boats with double channels, which have superior speed in still water, but the bow slamming load in waves is very serious, which affects the stability of navigation

Embodiment 1

[0020] combine Figures 1 to 5 , a planing boat with a three-channel structure is composed of two main hulls 1 and two sheets 2 of the same size. The three channels are the middle channel 4 which runs from the bow to the stern along the longitudinal direction of the hull at the bottom of the main hull 1, and two side channels which are respectively surrounded by the two side bodies 2 and the main hull. 3. The length of the sheet body 2 is smaller than that of the main hull 1, and the longitudinal length of the side channels 3 on both sides is also shorter than that of the middle channel 4. The middle channel 4 and the side channels 3 on both sides are symmetrically distributed with respect to the middle longitudinal section of the planing boat. The middle transverse section of the middle channel 4 is surrounded by the ship body 1 with straight walls on both sides and the straight top of the channel, with a smooth transition between the top and the side with a circular arc. ...

Abstract

The invention belongs to the technical field of planing boats, and particularly relates to a planing boat with a three-channel structure. The planing boat is the further improvement on a channel planing boat. Due to adoption of the design of three channels, bow made waves and wave loads can be absorbed during high-speed sailing, meanwhile, slamming loads of waves at the bow of the planing boat arereduced, planing postures are improved, and the sailing stability of the planing boat is improved. During high-speed sailing of the planing boat, an air film and a splashing water flow layer can be formed in each channel, and loads caused when waves directly slam the bow are reduced. Front air incoming flow can be guided to the boat bottom through the channels, accordingly, a boat body is elevated, drinking water of the boat is reduced, and the sailing resistance of the planing boat is reduced. The width of the channel at the middle portion is larger than the width of the channels on the twosides, the height of the channel is larger so that front incoming air can be widely absorbed to the bottom of the boat body, and meanwhile due to the large channel width, the made waves generated by amain boat body can be further absorbed.

Description

technical field [0001] The invention belongs to the technical field of planing boats, and in particular relates to a planing boat with a three-channel structure. Background technique [0002] Compared with conventional ships, planing boats can better combine the performance of hydrodynamics and aerodynamics because the lift force at higher speeds is formed by the combined action of hydrodynamic forces and aerodynamic forces. The function of the channel is to compress the air to flow to the bottom of the planing boat to lift the hull to reduce the draft when the planing boat is sailing at high speed. Planing boats have received extensive attention worldwide. [0003] At present, high-speed planing boats are generally trimaran planing boats with double channels, which have superior speed in still water, but the bow slamming load in waves is very serious, which affects the stability of navigation. Contents of the invention [0004] The purpose of the present invention is to...
