摘要: 据报道:德国航空航天中心正在研制一种使用表面主动冷却技术的Shefex-II锐边航天器,目的是提高航天器返回大气层时的安全性并降低维护成本.与美国航天飞机圆桶状的机身不同,在研的Shefex-II实验航天器的外形像子弹头,但机身如六角铅笔一样有棱边,其绝热瓦外形相对简单,可降低航天器隔热系统的维护成本关键词:...
The SHarp Edge Flight Experiment SHEFEX was established to investigate the flow around facetted surfaces for thermal protection of reentry vehicles and to deliver flight data in the hypersonic area with high loads. The experiment will concentrate on the validation of further developed structural concept...
