Embodiment Construction

[0024] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0025] combine Figure 1-9 , the hull is composed of two sheets 1 of the same size with sliding surfaces symmetrically arranged left and right, a connecting bridge 7 located between the two sheets 1, a pressurization chamber 8 in the connecting bridge 7, and a The vertical wing 9, the air cushion cabin 10 between the connecting bridge 7 and the two sheets 1, and the front and rear airbags 12, 11 are composed of parts.

[0026] The hull is supported by the static buoyancy of the sheet body 1 and the air cushion, and the sheet body 1 generates dynamic lift to provide auxiliary support at high speed. The pressurization chamber 8 sprays air to the air cushion cabin 10 to form an air cushion, lift the hull, reduce the draft, effectively reduce the wet surface area of ​​the ship, and reduce frictional resistance. At the same time, due to the reduced draft, the navigati...

Abstract

The invention aims to provide a partially-air-cushion-supported shallow-draft high-speed catamaran comprising two demihulls, vertical wings, a head air bag, a tail air bag and a cross structure. The cross structure is fixed between the demihulls, and comprises a hollow structure composed of an upper layer and a lower layer of plates, the hollow structure forms a pressurized chamber, the vertical wings are fixed at the bottom of the cross structure, air cushion chambers are composed of spaces formed by the two demihulls and the bottom of the cross structure, a hull stand is formed by the two demihulls, the cross structure and the vertical wings, the head air bag and the tail air bag are mounted at the head end and the tail end of the hull stand respectively, a tail gangplank is further mounted at the head end of the hull stand, a chamfer is arranged at the joint of the lower layer of the cross structure and each demihull, air holes are formed in each chamfer, and air in the pressurized chamber is injected into the air cushion chambers from the air holes to form air cushions so as to raise the hull stand and reduce draft. When the catamaran navigates in a hovering state, wetted surface is reduced greatly, and navigability is improved significantly.

Description

technical field [0001] What the present invention relates to is a kind of ship, specifically catamaran. Background technique [0002] A full cushion lift hovercraft is surrounded by nylon and other materials to form a soft apron, and the air is filled into the bottom by a fan to form an air cushion, and most of the propulsion uses air propellers or jets. The full lift hovercraft has amphibious capability and can walk on land. The effect of the air cushion greatly reduces the movement resistance and increases the speed of the ship. However, after the compressed air is ejected, it escapes to the surroundings, causing quite large waves and splashing a lot of water, which consumes a lot of energy. Therefore, although the speed of the ship has increased, the horsepower required is also very large. At the same time, the hovercraft has poor seakeeping performance, a large stall in sailing in wind and waves, and poor maneuverability. [0003] The catamaran has a large deck area a...
