水下缩比航行体热尾流的红外探测实验研究

根据缩比模型,建立了缩比红外成像实验测试系统,对水下航行体的体积、航行深度、运动速度、尾流排放等进行了缩比设计,设计了多种实验工况,可实现缩比目标模型红外尾流的静态和动态测试,一方面明确红外尾流的可探测性,另一方面掌握红外尾流可探测性的影响因素以及红外尾流的变化规律,为下一步工作奠定基础。

Experimental test system design for thermal wakes of submerged vehicle based on scale model

According to similarity principles, set up an infrared imaging experimental test system based on scale model, designed several different work conditions in the condition of scale model based vehicle volume, submerged depth, movement, wake discharging, and etc so that it is possible to realize the static and dynamic thermal wake detection tests of scaled vehicle. The aim is to determine the detectability of submerged vehicle thermal wakes on one side, and find the influencing factors at thermal wakes detection and changing rules of the wakes to lay a foundation for future work.
