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