箭上电缆防热设计及试验研究

摘要

对箭上电缆热环境进行总结，从对电缆热防护机理的分析着手，依据传热模式建立复合传热网络。调查并评价目前常用的防热材料和防护结构，提出了一体化系统结构设计理念。设计针对电缆防热考核系统的地面热结构试验，通过试验数据分析典型防护结构的温度响应。通过上述分析和总结，形成一套完善的设计、分析和验证流程。%In this paper, we focus on the thermal protection for rocket cable. The thermal environment was summarized firstly. A complex network of heat transfer was shown based on heat transfer theory. The materials and method for thermal protection was introduced, and then, a new idea about an integrated thermal protection system was bring out. The thermo-structure test aim at the cable was also described, therefore, the results which make a great impact on analyze were obtained. There by, a consummate flow chart including design, analysis and validate was built.
