Improvement of Pressure Exponent of Smokeless EMCDB Propellant by Granule-casting Process |
| |
| Abstract: | The granule casting process is applied to the shaping of elastomeric modified cast double base (EMCDB) propellant that shows good mechanical properties and plateau burning effect. The characteristics of low burning rate pressure exponent of smokeless EMCDB propellant are analyzed. The effects of combustion catalyst and NC content and RDX's particle size on the pressure exponent are studied. It is concluded that the granule casting process has advantages over silt casting process for EMCDB propellant. |
