Slender high-speed high-seakeeping double-channel multi-body planing boat

Abstract

The invention aims to provide a slender high-speed high-seakeeping double-channel multi-body planing boat, which comprises a main boat body and two demihulls, wherein the two demihulls are arranged on the two sides of the main boat body, are the same, and are connected with the main boat body from the positions of 10 percent of the length of the boat to the stern through channels with curved surfaces; the sections of the parts, before the positions of 45 percent of the length of the boat, of the demihulls are quadrangles with folded edges, the bottom surfaces and inner lateral surfaces of the quadrangles are inclined surfaces, and the sectional areas of the parts, before the positions of 45 percent of the length of the boat, of the demihulls are increased along with increase of the distance with the stem; the sections of the parts, after the positions of 45 percent of the length of the boat, of the demihulls are quadrangles with folded edges, and the sectional areas are unchanged. According to the planing boat, by the symmetric and slender demihulls, the speed of the planing boat is higher, and meanwhile, the seakeeping and seaworthiness of the planing boat are ensured; in a normal navigation process, the boat body ascends, a part of the demihulls and the channels are exposed from the water surface, the channels serve as planing surfaces, and an air layer is formed at the bottom of the boat, so that resistance can be effectively reduced, a damping and shock absorption function can be realized, and the seakeeping of the planing boat is improved.

Description

Technical field [0001] The invention relates to a ship, specifically a planing boat. Background technique [0002] As the earliest researched and developed ship that relies on hydrodynamic navigation, the planing boat has a wide range of applications in the military and civil fields. However, when a conventional planing boat is in motion, only a part of the hull is in contact with water. Although this reduces the resistance to a large extent, its stability and seakeeping performance are also greatly affected under the influence of waves. In many environments It is difficult to maintain normal sailing conditions in harsh waters. [0003] But at the same time, the research on the higher performance of the planing craft has never stopped. With the deepening of scientific research and the gradual improvement of manufacturing technology, the speed of the planing craft itself and the improvement of seakeeping have been significantly improved from different angles. The ability to comple...
