Burning Behavior of Composite Propellants with Fast-Burning Inclusions

The combustion characteristics of ammonium perchlorate-based composite propellants containing granulated fastburning energetic materials (FBEM) of different particle sizes have been studied in a constant-pressure bomb and combustion mechanism has been proposed. The use of FBEM of large particle size has been shown to allow not only a considerable increase in the burning rate, but also modification of the burning rate-pressure dependence.
