For better knowing the base bleed structure domestic and foreign in the serial linking construction of BB&Rocket compounded long-range projectile, We have analysed base-bleed structure grouping, working principle and main function of parts. We have validated the base bleed structure by adopting finite element simulation analysis methods and according to different structure in contrast test methods. Through the simulation analysis and the tests proving, We have given some key questions to be noticed in the designing of base bleed structure, in order to be provide references for engineering application of base bleed struccture in the serial linking BB&rocket compounded long-range projectile.
