Embodiment Construction

[0016] Hereinafter, the present invention will be described in more detail with examples in conjunction with the accompanying drawings:

[0017] Such as figure 1 As shown, the deck 1 of the hydrofoil catamaran, the two slices 2 and 3 of the hydrofoil catamaran, the front and rear hydrofoil pillars are 4 and 5, 10 and 11, respectively, are installed below the deck, and the slices Connected to the bottom. The front hydrofoil 6 is connected to the pillars 4 and 5, and the rear hydrofoil 9 is connected to the pillars 10 and 11. The two front flaps 7 and 8 are connected to the hydrofoil 6 through a transmission shaft 16, which is connected to an internal servo system. The pillar wings 12, 13 are connected to the pillars 10, 11 via shafts 17, 18, respectively. The flaps 14 and 15 are connected to the hydrofoil 9 via a shaft 19. The lengths of the pillars 4, 5, 10, and 11 mentioned above need to be selected according to the length of the pillar wings, and the area ratio of the pillar...

Abstract

The invention aims to provide a longitudinal movement attitude control device for a catamaran. The longitudinal movement attitude control device comprises a deck. A first sheet and a second sheet are respectively mounted at the left end and the right end of the lower side of the deck, a first front strut and a second front strut are respectively mounted at the front end of the first sheet and the front end of the second sheet, a first rear strut and a second rear strut are respectively mounted at the rear end of the first sheet and the rear end of the second sheet, a front hydrofoil is mounted at the lower end of the first front strut and the lower end of the second front strut, a rear hydrofoil is mounted at the lower end of the first rear strut and the lower end of the second rear strut, a first flap and a second flap are respectively arranged at the rear end of the front hydrofoil and are connected with the front hydrofoil by a first transmission shaft, a third flap and a fourth flap are respectively arranged at the rear end of the rear hydrofoil and are connected with the rear hydrofoil by a second transmission shaft, and the first transmission shaft and the second transmission shaft are respectively connected respective servo systems. The longitudinal movement attitude control device has the advantages that a heeling angle of the catamaran during pitching / heaving movement and rotation can be effectively reduced when the catamaran sails at a high speed, and accordingly the stability of the catamaran is improved.

Description

Technical field [0001] The invention relates to a hydrofoil catamaran. Background technique [0002] Due to its high-speed performance, hydrofoils have great advantages in passenger transportation. With the development of hydrofoil vessels, it also embodies considerable advantages in freight transportation. However, due to the lifting effect of the hydrofoil, the motion posture of the hydrofoil ship at high speed becomes severe, which limits its development. Summary of the invention [0003] The purpose of the present invention is to provide a catamaran longitudinal motion attitude control device that can effectively reduce the pitch / heave motion and the heel angle of the ship during high-speed navigation and improve the stability of the ship. [0004] The purpose of the present invention is achieved as follows: [0005] The longitudinal motion attitude control device of the catamaran of the present invention includes a deck. A first sheet and a second sheet are installed on the le...
