Embodiment Construction

[0016] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] Such as Figure 1~3 As shown, the "Arrow Shark" planing boat of the present invention includes: a planing boat hull, the rear end of the bottom of the planing boat hull is a triangular sliding surface 2, or a triangular sliding plate is provided to form a triangular sliding surface 2, and the triangular sliding surface 2 It is a triangular slab with an aspect ratio of 3.5-4.5, and a smooth transition is made at the apex of the triangle, and the length of the triangular sliding plate accounts for 30%-50% of the model length.

[0018] The bilge of the planing boat is provided with three layers of longitudinal ribs 6 from top to bottom, wherein the three layers of longitudinal ribs 6 form three layers of wave-pressing strips. Each longitudinal edge is a strip-shaped twisted triangular pyramid attached to the bilge of the hull. T...

Abstract

The invention relates to a shark-style planing boat, comprising a boat body. The rear end of the bottom of the boat body is provided with a triangular planing face, a front bilge of the boat body is in deep V shape, and a bilge portion includes three tiers of longitudinal ribs from top to bottom. The rear end of the bottom of the shark-style planing boat is provided with the triangular planing face, the middle bilge portion has a large ramp-up angle, and accordingly, good wave tolerance is provided; the front end is in deep V shape, the three tiers of longitudinal ribs form wave-holding strips, and accordingly, good speed performance is provided; a broken step at the tail makes it more convenient to adjust the center of gravity and mount a main unit; the shark-style planing boat is applicable to military ships under complex marine conditions and also has a promising application prospect in terms of civil ships.

Description

technical field [0001] The invention relates to the field of ships, in particular to an "Arrow Shark" planing boat, which has good seakeeping performance and resistance performance. Background technique [0002] High-speed planing boats are widely used in military and civilian applications due to their high-speed characteristics. The advantages of large-scale production in wartime have been valued by the navies of various countries. In terms of civilian use, such as traffic boats, high-speed passenger boats, ferries and other special work boats, etc. are also spread all over the world. High seakeeping planing boats are currently a hot research topic in the international shipbuilding industry. The main purpose is to allow small work boats and traffic boats to complete their tasks normally in high sea conditions, and to complete additional tasks such as assault investigations when needed. Since the 1970s, countries such as the United States, Israel, and the United Kingdom ha...
