| Abstract: | Long-march 5(LM-5)is the new generation large launch vehicle of China,and separation system is one of the key components of the development of LM-5.Nevertheless,remarkable characteristics,represented by large geometry scale of separated parts,heavy trust booster,long distance of first stage jettison and low stiffness large-scale payload fairings,challenge conventional strategy and method for Long-march LVs.The breakthrough and achievement on separation system in development of LM-5 are reviewed,which cover theoretical analysis,simulation technology and experiment validation. |
