M-shaped wave absorbing glider with bulbous bow

Abstract

The invention relates to a M-shaped wave absorbing glider with a bulbous bow. The M-shaped wave absorbing glider with the bulbous bow comprises a glider body consisting of a ship bottom plate, a deck,a left ship side plate, a right ship side plate, a front side plate and a rear right side; the bulbous bow is arranged at a bow; the bulbous bow comprises a bulbous bow bottom with a V-shaped sectionand a bulbous bow upper part with a rectangular section; a rigid left wave absorbing side wall is arranged on the left ship side plate; a rigid right wave absorbing side wall is arranged on the rightship side plate; and therefore, the rigid left wave absorbing side wall, the left ship side plate, the ship bottom plate / the bulbous bow, the right ship side plate and the rigid right wave absorbingside wall form an M-shaped glider bottom; the rigid left wave absorbing side wall and the left ship side plate form a left sliding channel; the ship bottom plate and the bulbous bow form a middle water drainage body; and the right ship side plate and the rigid right wave absorbing side wall form a right sliding channel.

Description

technical field [0001] The invention relates to the technical field of ship structures, in particular to an M-type wave-suppressing planing boat with a bulbous bow. Background technique [0002] A planing boat is a surface-type ship that uses various principles of hydrodynamic or aerodynamic forces to change the hydrodynamic components supporting the hull. When sailing at low speeds, the hull is in a displacement sailing state or in a transitional state. When sailing at high speeds, the entire hull is Hold up, only a small part of the surface of the hull is in contact with the water, the static buoyancy is very small, and the hull is almost completely supported by the hydrodynamic lift. This ship type has the hydrodynamic characteristics of various types of ships. The excellent hydrodynamic performance of the planing boat makes it widely used in small boats, such as patrol boats, fishing boats, service boats, ambulance boats, entertainment boats and sports boats.

AI Technical Summary

Problems solved by technology

The M-shaped channel planing boats that have emerged in recent years are composed of a relatively large central main hull and slender side panels on both sides. During navigation, the side panels generate very little wave-making, while the main hull Most of the wave-making generated by the body is absorbed by the channel, combined with the air entering the channel from the stamping effect, it provides aerodynamic (water) lift for the channel, so that the wave-making energy of the main body can be recovered, and the total resistance can be reduced. reduction; the design of the planing boat with the above structure is to reduce the wave-making effect of the hull, but although the above-mentioned design can reduce the wave-making effect on both sides of the hull, it cannot eliminate the wave-making effect at the front end of the hull
