ADVANCES IN HYPERVELOCITY IMPACT DYNAMICS AND SPACECRAFT PROTECTION RESEARCH

Hypervelocity impact dynamics and spacecraft protectionas an important part of hypervelocity impact technology, is reviewed inthis paper. Its research background is outlined. Itsresearch progress covers the following five aspects: making hole in the thick board,penetration in the critical thick board, forming debris cloud from the thinboard, experimental simulation technique and numerical simulation technique.The damage effect of hypervelocity impact spacecraft is analyzed. Thespacecraft protection requirements are given, and the project design andperformance of the spacecraft protection structure are discussed.
