Launching stability is a key constraint in the design of ultra-light artillery. Through the analysis of the firing dynamics of the whole artillery, the influences of two kinds of buffer arrangement schemes on the firing stabilities of an artillery designed with tranditional structural principle (A-type) and an artillery designed with new structural principle (B-type) are analyzed, and the corresponding optimization design of buffer characteristics is also carried out. The results show that the effect of backtrail buffer on improving the firing stability of A-type artillery is not obvious; it is beneficial for B-type artillery to improve the stress on the backtrail and increase the firing stability by adding the backtrail buffer on its top.
