摘要
Abstract
[Objectives]As the ship side wet exhaust system is widely equipped on many stealth frigates,it is necessary to study its infrared signature suppression(IRSS)effect.[Methods]In this paper,the IRSS prin-ciple of the wet exhaust system is analyzed,a mathematical model of the system based on an exporting vessel is built,the exhaust system outlet temperature is simulated and a real vessel infrared signature test is carried out.[Results]The simulation results show that the outlet temperature is reduced to 60℃.Compared to pop-ular funnel IRSS devices,the infrared signature of the 3-5 µm wave band can be reduced.The real vessel in-frared signature test results show that the outlet temperature is reduced to 66.7-70.0℃and the infrared signa-ture intensity is 1.39 W/s.[Conclusions]The results of this study can provide useful references for the ap-plication of the ship side wet exhaust system in the naval ship IRSS field.关键词
