弹道式再入飞行器已使用在多个型号上,确保安全再入的问题基本上已经解决。在解决了再入生存性问题之后,对再入飞行器的研究重点已转到如何提高再入飞行器的性能上。美国从六十年代后期到八十年代初,也一直在研究和开发高性能端头,执行了诸如“高级弹道式再入系统计划”、“被动式防热端头技术计划”、“再入飞行器性能技术计划”等大型研制计划。本文对弹道式再入飞行器的高性能端头和解决的技术途径提出一些分析和看法。
Ballistic reentry aircraft have been used on multiple models to ensure that the issue of safe reentry has been largely solved. After addressing the issue of re-entry survivability, the focus of research into reentry vehicles has shifted to how to improve the performance of reentry vehicles. Since the late 1960s and early 1980s, the United States has also been researching and developing high-performance terminals that implement such programs as the Advanced Ballistic Reentry System Plan, Passive Thermal End Technology Plan, Reentry Vehicle Performance Technology Plan "and other large-scale development plan. This article gives some analysis and opinions on the high performance of ballistic reentry aircraft and the technical solution.
