Description

Technical Field

[0001] This utility model relates to the field of hydrofoils, and in particular to a hydrofoil for water transportation vehicles. Background Technology

[0002] Water transport generally refers to vehicles that travel on water. There are various types of water transport, including ships, boats, rafts, and hydrofoils. Among them, hydrofoils are usually boats with hydrofoils that are submerged in water. When traveling at high speeds, the weight of the boat is entirely supported by the lift generated by the water on the hydrofoils, which makes the entire hull leave the water surface, reducing water resistance and thus achieving higher speeds.

[0003] Hydrofoils typically consist of a front wing and a rear wing. Existing front and rear wings usually have the following disadvantages: (1) They are assembled as a single unit on the hydrofoil boat, which increases the transport volume and affects the on-site assembly efficiency. They also have a large weight. Therefore, it is necessary to design the hydrofoil in a modular assembly manner to reduce the transport volume and improve the on-site assembly efficiency; (2) The structural stability is insufficient; (3) The sailing resistance is large.

Detailed Implementation

[0038] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0039] This utility model provides, for example Figure 1-3The hydrofoil shown is for a waterborne vehicle and includes a front wing structure 1, a rear wing structure 2, a first assembly 4, and a second assembly 5. The front wing structure 1, rear wing structure 2, first support member 3, first assembly 4, second assembly 5, and second support member 6 are integrally molded from carbon fiber material. The manufacturing method of the front wing structure 1, rear wing structure 2, first assembly 4, and second assembly 5 involves carbon fiber lay-up, vacuum sealing, and high-temperature curing in an autoclave. Internally, it incorporates two 30mm wide foamed reinforcing support beams, which are compositely molded using a foaming process and structural adhesive bonding. Innovatively, three-dimensional woven carbon fiber prepreg is used to fabricate the main load-bearing components. Through topology optimization design, an equal-strength structural distribution is achieved. This structure features high strength, light weight, and long service life. The front wing structure 1 has a first support member 3 inside, which facilitates connection with the hydrofoil and supports the connection of the front wing structure 1. The front wing structure 1 is U-shaped, and the adjacent rear wing structure 2 is symmetrically arranged. The rear wing structure 2... The internal structure is equipped with a second support member 6, which facilitates the support between the hydrofoil and the rear wing structure 2. The rear wing structure 2 is C-shaped. The first assembly 4 is located on the front wing structure 1 and is used to assemble and fix the front wing structure 1. The first assembly 4 and the second assembly 5 are directly plugged into the hydrofoil and locked with bolts, which facilitates disassembly, replacement and maintenance.
