Effect of procedure parameters on the properties of cast RDX-CMDB propellant

It was studied the influence of kneading time, curing time, curing temperature and cessation angles on the burning rate, pressure exponent and mechanical properties of solid propel lants consisting of NC granules, oxidizer and combustion stabilizer etc. The results show that the interface properties of mixed solid materials affect the infusion of NG into NC granules, which controls the burning rate and pressure exponent of propellants. The kneading time of RDX-CMDB slurry affects the combustion and mechanical properties. The combustion and mechanical properties are improved by the increase of curing time at 701.
