A comprehensive utilization technology of the exhaust gas of the ship's main engine, which belongs to the application field of Ship Stealth and the technology of recycling use of tail gas. In this paper, we propose to reduce the number of bubbles in the tail gas by ship exhaust. This technology will exhaust the exhaust gas from the main engine and discharge it underwater, which can conduct infrared and visual stealth of high temperature exhaust gas. It can be a large number of bubbles using the tail gas cast, through micro bubble coalescence and wake, carry, neutralization, produce effective jamming on the ship wake bubbles, continuous capture attract micro bubble wake in large buoyancy turbulence to overcome obstacles, quickly surfaced, to eliminate the wake effect. This method reduces the space occupancy of the ship, and has little change to the hull structure. More close to actual use, it is the simplest and direct means to carry out the bubble of the tail flow. It provides a more convenient way to truly realize the application of the new technology for the suppression of the air bubble wake. To eliminate the bubbles this technology can realize the ship fundamentally, and has the advantages of rapid, flexible layout structure is enabled, it can be used as the ship engine exhaust plume based elimination technology, solve the existing technology in the wake of the elimination of releases, limit generation device layout complex and high energy consumption and other factors of the problem. It has good application prospect.

舰船主机尾气它隐与自隐利用技术
本专利技术涉及一种舰船主机尾气它隐与自隐利用技术,其属于舰船隐身及对主机尾气循环利用技术的应用领域。
技术介绍
舰船尾流的范围大,持续时间长,不易消除,不易伪装。而且舰船尾流中存在包括气泡场等十几种物理场,以及微波、红外、声学和光学场等,且在短时间内不会消除。对军事作战而言,获取舰船尾迹信息有着至关重要的作用,因为单一的舰船目标容易伪装,然而空间范围较大的尾迹却难以躲避。尾流自导鱼雷主要基于尾流的光学信号、磁学信号、热学信号、放射性信号和气泡场信号等。在现有研究中,气泡场是众多物理场中最易被发现,也是被自导鱼雷利用最多的尾流物理场。海水的表层中,微气泡会被吸入由湍流边界层和螺旋桨形成的漩涡中,漩涡影响大,持续时间长,使得气泡在水中留存时间更长,被探测利用的距离更长。这对舰船水面安全构成了严重威胁。针对气泡尾流场隐身方案,各国也都积极进行研究。当前,国内外对抗尾流自导鱼雷技术主要包括硬杀伤性对抗、软杀伤性对抗和非杀伤性对抗三类。其中硬杀伤性武器的有效发挥依赖于对来袭鱼雷及时准确的判断,然而当前没有成熟的技术能够完成对鱼雷有效探测与识别 ...
