Abstract: The agglomeration phenomena of metal particles in propellant combustion enviroments have great effects on the performance of solid rocket motors. On the basis of general description of agglomeration phenomena some reviews on surface reaction layer model for DB propellant agglomeration and on pocket models for composite propellant agglomeration are presented in this paper. In view of some anomalies on effects of burning rate and pressure, some reviews on"sub-pocket"mechanism and"inter-pocket"mechanism recently are also discussed.
