Embodiment Construction

[0018] Such as figure 1 with 2 As shown, the present invention includes: the lower body 1, 2 of the left and right sides of the catamaran, the pillars 3, 4, the connecting bridge 5, the front and rear hydrofoil 6, 7 and the front and rear hydrofoil pillars 8,9. The lower bodies 1 and 2 of the left and right sides of the catamaran are respectively connected by slender struts 3 and 4 and the connecting bridge 5 on the upper part of the hull. At the same time, the lower bodies 1 and 2 of the left and right sides of the catamaran The front and rear hydrofoils 6 and 7 are arranged front and rear, and the front and rear hydrofoils 6 and 7 are respectively provided with front and rear hydrofoil pillars 8 and 9 connected to the connecting bridge 5.

[0019] The lower main bodies 1, 2 of the two left and right lamellas of the catamaran are two slender bodies with circular or elliptical cross-sections. There are an inflow section, a parallel middle body and an outflow section. The ratio to...

Abstract

The invention relates to a double-body small-water plane hydrofoil combined high speed ship, belonging to ship engineering technical field, comprising: bottom main bodies of left and right piece bodies, posts, connection bridge, front and rear water wings and front and rear water wing posts, the bottom main bodies are connected with the connection bridge through the posts, and simultaneously the front and rear water wings are arranged front and rear between the bottom main bodies, respectively, the front and rear water wings are respectively provided with the front and rear water wing posts to connect with the connection bridge. The invention depends on the lift force of the water wings bears to bear part of hydrostatic floating force, able to correspondingly reduce drainage volume of the bottom bodies and wet surface area, rising wave resistance and frictional resistance, and thus raising the speed, and the invention can normally and safely sail at high speed.

Description

Technical field [0001] The invention relates to a ship in the technical field of ship engineering, in particular to a twin-body small waterplane surface hydrofoil compound high-speed ship. Background technique [0002] In recent years, with the diversification of maritime transportation methods and the active development of marine resources by mankind, the requirements for ship performance are gradually changing. The concept of "time value" has made people increasingly demanding the speed of various vehicles. The increase in ship speed in waterway transportation is an inevitable trend. Therefore, how to reduce the resistance of ships and how to reduce the resistance of high-speed ships to make waves has become one of the main tasks of shipbuilders. On the other hand, in severe sea conditions, the ship will produce abrupt swaying motion, causing seasickness, waves on the deck, slamming of the crew and passengers, water out of the propeller, speeding of the main engine, stalling, e...
