Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, a trimaran comprises a main hull 2-5 and two sheets, wherein the two sheets are a first sheet 2-3 and a second sheet 2-4, the first sheet 2-3 and the second sheet 2-4 are symmetrically arranged on two sides of the main hull 2-5, the first sheet 2-3 and the second sheet 2-4 are connected with the main hull 2-5 through an annular connector 1-2, and are connected through the annular connector 1-2, so that the strength of the trimaran can be increased to a certain extent, and the strength problem of a traditional connecting bridge is improved.
The annular connector 1-2 and the main ship body 2-5 form a whole through the wing body fusion body 1-4. The wing body fused structure body can reduce the friction resistance by utilizing the characteristic of small infiltration area. The layout mode of wing body fusion has the advantages of light structure, large volume and small resistance, and has the advantage of large deck area compared with the traditional layout characteristics.
The main ship body 2-5 adopts a flying shear type bow. The flying shear type bow is also called an extension deck type bow, is designed to be a concave curve above a waterline and has a larger deck overhanging part. The deck is not easy to wave, the deck area can be enlarged due to the fact that the head part has large overhang, arrangement of an anchor machine and ship mooring equipment is facilitated, good wave breaking performance is achieved, the side board is inwards inclined, and good stability is provided. The design of deep V-shaped ship shape improves the motion of the ship body and reduces the rising waves.
Two coaxial double-propeller ducted fans are symmetrically arranged on the wings of the wing body fusion body 1-4, and are respectively a first coaxial double-propeller ducted fan 2-1 and a second coaxial double-propeller ducted fan 2-2, and the first coaxial double-propeller ducted fan 2-1 and the second coaxial double-propeller ducted fan 2-2 can generate certain lift force, so that the resistance of the ship during high-speed navigation is reduced.
The annular connection 1-2 is streamline, which is beneficial to reducing air resistance generated during high-speed running.
The length of the main hull 2-5 is 6 times the length of the blade, where the resistance performance of the boat is the best.
The bow of the main ship body 2-5 is additionally provided with a wedge-shaped wave pressing body 3-1. The main hull 2-5 of the trimaran adopts and additionally arranges a wedge-shaped wave pressing body 3-1, which can ensure the excellent resistance performance at a high-speed section.
The displacement volume ratio of the side body to the main ship body 2-5 is 1/20, the Froude coefficient is Fr =0.35, the drag reduction effect is outstanding, and the propulsion efficiency is improved.
Although the present invention has been described with reference to the preferred embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention as defined by the appended claims.
