火箭发动机羽流红外特性研究概述

Review of Research on Infrared Radiation Signatures of Rocket Exhaust Plume

介绍了国内外火箭发动机羽流红外特性的研究进展及实验研究方法,总结了计算发动机羽流红外特性常用的求解方法及其特点,提出国内应当在辐射模型的完善及与流场计算的耦合度、高空辐射模型的建立、实验数据获取等方面开展更深入的研究工作。

The situation of international and domestic research on the infrared （IR） radiation signatures of rocket exhaust plume is briefly introduced. The commonly solutions and their characteristics for the IR signatures of rocket exhaust plume are summarized. It is pointed out that more research works should be done in the fields such as the radiation model optimization, the coupling of the radiation calculation and flow field simulation, the high altitude radiation model building and valuable measurement data acquirement.
