Problems solved by technology

However, when a ship sails at sea, it will produce a certain roll angle in some cases. When the roll angle of the hull is greater than the inclination angle of the superstructure, it will cause the radar wave to irradiate the hull and directly reflect back, making the ship The RCS value is increased in certain rolling states

Embodiment Construction

[0016] A ship absorbing structure of the embodiment of the present invention, such as figure 2 As shown, the installation base plate 1 is connected to the hull outer plate, the inner gusset plate 2 is fixedly connected to the installation base plate 1 , the wave-absorbing dressing 3 is fixedly connected to the inner gusset plate 2 , and the surface coating 4 is fixedly connected to the wave-absorbing dressing 3 . When the ship rolls, the inner and outer corners of the inner corner plate 2 can effectively scatter radar waves within a certain incident angle range, and after the inner corner plate 2 is fixedly connected with the installation base plate 1, a certain air barrier can be formed. Layer, improve the heat insulation effect of the present invention.

[0017] Such as image 3 Shown is a schematic diagram of scattered radar waves of the present invention at various roll angles. After analysis, when the ship is in the state of rolling +20°, +10°, 0°, -10°, -20°, after th...

Abstract

The invention discloses a ship wave absorbing structure which comprises an installing base plate, an internal bevel plate, wave absorbing dressing and a surface coating. The installing base plate is connected with a ship body outer plate, the internal bevel plate is connected with the installing base plate, the wave absorbing dressing is connected with the internal bevel plate, and the surface coating is connected with the wave absorbing dressing. According to the ship wave absorbing structure, a leaning angle of an existing ship superstructure is maintained, overall arrangement and internal cabin capacity of a ship are not affected, the leaning angle of the ship is enlarged from the internal structure, and a radar wave scattering effect of the ship in various rolling states is improved. When radar waves pass the wave absorbing dressing, echo strength is attenuated, an RCS value of the ship is further reduced, and invisibility and safety of the ship are improved. The ship wave absorbing structure has a certain heat insulation performance and can replace an existing ship heat-insulating insulating material, and the weight of the ship is reduced.

Description

technical field [0001] The invention relates to the overall stealth design of ships, especially the wave-absorbing structure of ships. Background technique [0002] At present, in order to reduce the radar wave reflection area (RCS) and improve its own invisibility and safety, the superstructure is usually designed with a certain inclination angle (generally about 7°), so that the radar wave will not directly irradiate the hull. Reflected back, but reflected upwards at a certain angle to reduce the intensity of radar echoes and reduce the RCS value of the hull, such as figure 1 shown. However, when a ship sails at sea, it will produce a certain roll angle in some cases. When the roll angle of the hull is greater than the inclination angle of the superstructure, it will cause the radar wave to irradiate the hull and directly reflect back, making the ship The RCS value is increased in some rolling states, which is easy to be found and locked by enemy radar. In order to redu...
