Embodiment Construction

[0033] The present invention is described in more detail below in conjunction with accompanying drawing example:

[0034] combine figure 1 and 2 , the present invention includes: hydrofoils 4,9, hydrofoil struts 5,10, left and right symmetrical flaps 7,8,12,13 on the hydrofoil struts, column wing rudders 6,11 on the hydrofoil struts, connectors 14,17 , the connecting bodies 15,18 of the column wing rudder and the hydrofoil pillar, and the connecting shafts 16,19 of the flap and the hydrofoil. The hydrofoils 4, 9 of the present invention are fixedly connected with the two pieces 1, 2 of the catamaran, and the specific installation position and installation angle of attack of the hydrofoils need to be determined according to the specific design requirements. The hydrofoils 4, 9 are fixedly connected to the hydrofoil struts 5, 10 through connecting bodies 14, 17, and the hydrofoil struts 5, 10 are fixedly connected to the upper connecting body 3 of the catamaran. The left and...

Abstract

The invention provides a multifunctional control device of a small waterline plane ship hydrofoil and column rudder, comprising two hydrofoils and a column rudder mechanism; each hydrofoil and the column rudder mechanism comprise hydrofoils; a hydrofoil strut fixed on the hydrofoil, two wing flaps symmetrically distributed on the hydrofoil and at the both sides of the hydrofoil strut and a columnrudder arranged on the hydrofoil strut; two hydrofoils and the column rudder mechanism are respectively installed at the front part and the rear part of a small waterplane area twin-hull ship; two sheet bodies of the hydrofoil and the small waterplane area twin-hull ship are fixedly connected according to a certain installation angle; the hydrofoil strut is fixedly connected with a connection body at the upper part of the small waterplane area twin-hull ship. The multifunctional control device of the invention has multiple functions, can shorten transient time from hullborne operation to foilborne operation, weaken heave motion and pitching motion of the small waterplane area twin-hull ship, weaken rolling motion of the catamaran, control inclination angle of the ship, has course control function, can effectively shorten steering gyration radius, and improve the safety, navigability and maneuverability of the small waterplane area twin-hull ship.

Description

technical field [0001] The invention relates to an auxiliary equipment of a high-speed catamaran in the technical field of ship engineering, in particular to a control device of a small waterplane surface craft. Background technique [0002] With the development of the shipping industry and the development and utilization of marine resources, people's performance requirements for various vehicles are also gradually changing. The development of high-performance ships has become the development trend of the world's shipbuilding industry, and various high-performance ships have emerged, such as high-speed catamarans, small waterplane area catamarans, wave piercing ships, composite catamarans, etc.; A typical high-speed catamaran consists of two slender monohulls (called hulls) connected at the top by deck bridges. Because the high-speed catamaran divides a single hull into two pieces, each piece is thinner and longer, thereby reducing the wave-making resistance and making it h...
