Hydrofoil catamaran inner flap/outer flap combined automatic control device

Abstract

The invention aims to provide a joint automatic control device for inner flaps / outer flaps of a hydrofoil catamaran. The joint automatic control device comprises a catamaran. Two sheets are respectively mounted at the left end and the right end of the lower side of the catamaran, a front hydrofoil is mounted at the front ends of the lower sides of the two sheets, a rear hydrofoil is mounted at the rear ends of the lower sides of the two sheets, a first outer flap, a second outer flap, a first inner flap and a second inner flap are respectively mounted at the rear end of the front hydrofoil by the aid of a first connecting shaft, a third outer flap, a fourth outer flap, a third inner flap and a fourth inner flap are respectively mounted at the rear end of the rear hydrofoil by the aid of a second connecting shaft, and the first outer flap, the second outer flap, the third outer flap, the fourth outer flap, the first inner flap, the second inner flap, the third inner flap and the fourth inner flap are respectively connected with respective servo motors. The joint automatic control device has the advantages that the joint automatic control device is simple in structure and reasonable in design, multifunctional and multi-objective cooperative control is implemented, and the safety, the seaworthiness and the maneuverability of the hydrofoil catamaran are improved; the front hydrofoil and the rear hydrofoil are respectively connected with the two sheets of the hydrofoil catamaran, so that the mechanical structural strength is improved.

Description

technical field [0001] The invention relates to a hydrofoil catamaran. Background technique [0002] Although high-performance ships such as hovercraft, hydrofoils, and planing craft have many advantages, they also have many disadvantages. The layout structure of high-speed catamaran is relatively simple, and it has a relatively spacious deck area and good lateral stability, but its hydrodynamic performance is poor at high speed, and it has high linear acceleration and poor habitability in waves. . Ordinary hydrofoil boats have problems of vertical stability and longitudinal stability. With the progress of the times and the rapid development of science and technology, in the early 1990s, the development of composite high-performance ships that absorbed the unique advantages of various high-performance ships reached a climax. The hydrofoil catamaran consists of two symmetrical pointed bilge slender hulls and a hydrofoil installed near the keel between the two hulls. A hyd...

AI Technical Summary

Problems solved by technology

However, due to the decrease of the draft of the hull, the self-stability deteriorates, and the hull is easily disturbed by the outside world such as wind, waves, currents, etc., so that the pitching / heaving movement of the ship is severe, especially when sailing in head waves

The catamaran structure of the hydrofoil catamaran makes the ship have good lateral stability, but when turning at high speed, it will produce serious heeling. Excessive heeling angle will not only reduce the seaworthiness of the ship, but even risk the hull capsizing
