本文介绍了航天飞机防热系统三种方案(不完全重复使用方案、改进防热方案和完全重复使用或永久性防热方案),在对三种防热方案进行分析评价的基础上,分析了他们的发展趋势及防热材料研制发展的动向,从而得出:航天飞机的防热方案应以实现发展阶段内的可靠性和先进性为目标,根据特定的具体要求及客观可能性提出;不存在某种固定的模式。实现材料合金化、复合化和构件结构积木化,是航天飞机防热材料的发展方向。
This paper introduces three schemes of shuttle thermal protection system (incomplete reuse scheme, improved thermal protection scheme and completely repeated use or permanent thermal protection scheme). Based on the analysis and evaluation of three thermal protection schemes, Their development trend and development trends of heat-proof materials, draws a conclusion that the space shuttle’s heat-protection plan should be based on the specific requirements and the objective possibility to achieve the reliability and advancement in the development stage; There is some fixed pattern. To achieve the material alloy, composite and building blocks of building blocks, is the space shuttle heat-resistant materials development.
