Problems solved by technology

Conventional planing boats are subject to greater resistance when gliding at high speed, and at the same time, they are subjected to very severe wave loads in waves, and the requirements for structural strength are relatively high, so the sea area of ​​activities is greatly restricted

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] see Figure 1-6 , the present invention provides a technical solution: a three-body channel planing boat with an ax-shaped bow, including a hull 1, the aspect ratio of the hull 1 is not less than four, which can greatly reduce the resistance of the hull 1 when sailing , the upper surface of the hull 1 is provided with a deck 2, and one side surface of the hull 1 is provided with a stern 3, and the other side surface of the hull 1 is provid...

Abstract

The invention discloses a three-hull slotted boat with an axe-shaped bow, which comprises a main hull, a sheet hull and a slotted channel. The main hull in the middle is larger; The slender hulls on both sides and the main hull are connected at the top and form transistion by a channel. The upper surface of the hull is provided with a deck, the stern of the hull is outwardly provided with an axe-shaped bow from the stern seal plate, the side surface of the axe-shaped bow is provided with a bow post, and the middle part of the side surface of the hull is provided with a freeboard. The seakeeping, stealth, and loading capacity of the hull, and can adapt to harsh sea conditions are improved. This type of boat is suitable for yachts, high-speed rescue boats and high-speed interceptor boats, with high speed and excellent stability. The aspect ratio of the main hull is not less than four, which can greatly reduce the resistance of the main hull when sailing, and at the same time, the aerodynamic lifting force generated by the hull passing through the channel when the hull sails at high speed can further improve the gliding posture and improve the rapidity of the ship while reducing the sailing resistance.

Description

technical field [0001] The invention relates to the technical field of surface ship technology speedboats, in particular to a three-body channel planing boat with an ax-shaped bow. Background technique [0002] Conventional planing boats are the earliest researched boats relying on hydrodynamic navigation. Many navies maintain a considerable number of planing boats, and they are also one of the most widely used high-performance boats in civilian ships. Conventional planing boats are subject to greater resistance when gliding at high speed, and at the same time, they are subjected to severe wave loads in waves, and the requirements for structural strength are relatively high, so the sea area of ​​activities is greatly restricted. [0003] Ordinary high-speed planing boats, that is, single-body planing boats mainly support the weight of the boat with hydrodynamic lift. Three-body channel planing boats are a combination of conventional planing boats, high-speed multi-hull ships...
