摘要
基于相似原理建立了缩比实验测试系统,针对目标大小、潜深、运动、尾流释放等设计了多种不同的工况,可实现缩比模型下热尾流探测的静态和动态测试,一方面确定水下目标热尾流的可探测性,另一方面探索热尾流探测的影响因素和变化规律,为下一步工作奠定基础。
According to similarity principles, an infrared imaging experimental test system was set up based on scale model, several different working conditions in the condition of scale model were designed based vehicle volume, submerged depth, movement, wake discharging, and etc., so that it was possible to realize the static and dynamic thermal wake detection tests of scaled model. The aim is to determine the detectability of thermal wakes from submerged vehicle 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.
