Hydrofoil and planing combined boat with retractable front hydrofoil

Abstract

The invention discloses a hydrofoil and planing combined boat with a retractable front hydrofoil, which comprises a boat body and a propulsion device at the stern of the boat body; the bottom surface of the stern of the boat body serves as a planing surface; the mid-front part of the boat body is a single hull; the mid-rear part of the boat body takes a tri-body boat shape and comprises a middle boat body and side boat bodies; the two sides of the bottom of the middle boat body extend outwards to form arc-shaped grooves which constitute lateral splashing water channels; the front hydrofoil is arranged under the bottom of the mid-front part of the boat body through vertical pillars on the two sides; a pillar axially-moving mechanism is arranged in the boat body; and when the front hydrofoil goes up to the highest position to be inside the bottom of the boat body completely, the planes on the two sides of the front hydrofoil are clung to the two sides of the front part of the boat body to become a part of the outer surface of a fairing of the boat body. The hydrofoil and planing combined boat combines high speed of a planing boat and good seakeeping property and small wave making property of a hydrofoil, overcomes the defect that the planing boat or the hydrofoil is not suitable to rush to a shallow, effectively solves the problem of severe lateral splashing caused by single-hulled or twin-hulled planing, and can serve as a hydrofoil as well as a planing boat.

Description

technical field [0001] The invention relates to a composite wing skid, in particular to a composite wing skid capable of carrying people on water and having the functions of a planing boat and a hydrofoil boat for transportation, tourism and sightseeing, and belongs to the technical field of high-performance ships. Background technique [0002] Planing boats and hydrofoil boats are important members of the high-performance boat family. They are currently being built and used in large numbers at home and abroad. They are widely used, such as yachts, passenger boats, racing boats, traffic boats, etc. for civilian use, and for military use. The torpedo boats, missile boats, gunboats, submarine hunters, reconnaissance boats, mine-laying boats, etc., generally have a displacement of less than 200 tons and a speed of 50 to 80 knots. [0003] When the planing boat glides at high speed on the water surface, most of the weight of the planing boat is supported by hydrodynamic force, a...

AI Technical Summary

Problems solved by technology

Its advantage is fast speed, but its disadvantages are large vibration, severe impact, poor heading stability, and strict requirements for weight distribution. This shortcoming seriously limits the weight arrangement of the boat.

[0004] A hydrofoil boat is a high-speed small boat with hydrofoils installed on the bottom of the boat. When a hydrofoil boat sails at high speed on the water surface, it relies on the water lift generated by the hydrofoil to completely lift the hull out of the water. Under the same displacement and propulsion power, its fast Compared with the planing boat, the performance is greatly improved, and it overcomes many shortcomings of the planing boat, but it has a large stall in waves, and at the same time, the propulsion device is more complicated and the cost is high
