Simplified Burn-Rate Model for CMDB Propellants [PDF]
Defence Science Journal, 1990 A single model has been proposed to predict the burning rates of bimodal AP,RDX and aluminum containing CMDB propellants. This is done in terms of the respective physical constants on the basis of a recently developed model of combustion of CMDB propellants.
