Abstract

The invention discloses an adjustable multi-layer hydrofoil catamaran. The adjustable multi-layer hydrofoil catamaran comprises adjustable multi-layer hydrofoils, two pairs of single hulls, auxiliary hydrofoils, propellers and a deck bridge connecting the two pairs of single hulls. Wherein the adjustable multi-layer hydrofoil is arranged between the two pairs of single hulls, the deck bridge is connected with the two pairs of single hulls, and the auxiliary hydrofoils are arranged on the two sides of the single hulls. The invention further provides an adjusting method. The adjustable multi-layer hydrofoils and the two single ship bodies of the catamaran are combined together, the existing advantages of the catamaran are guaranteed, meanwhile, the seaworthiness and rapidity of the catamaran are further improved by adjusting the multi-layer hydrofoils, the lift force of the hydrofoils and the water immersion area and the floating state of the ship bodies are changed by adjusting the depths and the relative positions of the multi-layer hydrofoils, and the ship bodies are more stable. The seakeeping performance of the catamaran is improved, and the purpose of improving the seaworthiness and rapidity of the catamaran is achieved.

Description

technical field

[0001] The invention relates to a catamaran, in particular to an adjustable multi-layer hydrofoil catamaran and an adjustment method thereof. Background technique

[0002] With the continuous development of marine resources by human beings and the development of the world shipping industry towards the direction of high-speed passenger and freight transportation. The requirements for ships are getting higher and higher, and various high-performance ship types have emerged. Catamaran is a high-performance ship developed in recent years. The hull of the catamaran is composed of two hulls and a connecting bridge. The deck area is greatly increased, and the stability is greatly improved compared with that of the monohull. The displacement is mainly concentrated in the lower hull deeper from the water surface, and the wave resistance Smaller than a monohull, especially at high speeds. The hydrofoil is a kind of ship that is equipped with hydrofoils immersed in t...

Embodiment Construction

[0035] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments, and it should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention.

[0036] An adjustable multi-layer hydrofoil catamaran such as Figures 1 to 10 As shown, including a catamaran hydrofoil 100, an adjustable multi-layer hydrofoil 140, a first auxiliary hydrofoil 122, a second auxiliary hydrofoil 132, a propeller 121, and a propeller two 131, the catamaran hydrofoil 100 includes The first monohull 120 and the second monohull 130 which are arranged at a relative interval are connected by a deck bridge 110 .

[0037] Between the first monohull 120 and the second monohull 130, an adjustable multi-layer hydrofoil 140 is arranged at the front and lower position in the middle, and the adjustable multi-layer hydrofoil 140 is respectively connected with the two. The adj...
