航天轨道器系统,更确切地说,航天飞机是覆盖有防热材料的传统铝合金结构,防热材料的作用是为了再入时使其结构件温度不超过177℃。 那么防热系统的工作状况如何呢?洛克韦尔国际空间研究分部的专家们认为:“防热系统工作得比预想的还要好。在高级材料和加工工程协会的第27届国家讨论会上,克莱西和史 Aerospace orbiter systems, to be more precise, the space shuttle is a traditional aluminum alloy structure covered with a heat-resistant material whose function is to keep the temperature of its structure up to 177 ° C during reentry. So what’s going on with the heat-protection system? Experts at the Rockwell International Space Research Division argue that “the heat-protection system worked better than expected.” At the 27th National Symposium of the Advanced Materials and Process Engineering Society , Cressy and history
