Abstract | ||||
ABSTRACT The combustion behavior, flammability limits and ballistic properties, of composite low oxygen content propellants were studied experimentally by using propellant formulations based on hydroxy-terminated polybutadiene pre-polymer (HTPB) / ammonium perchlorate oxidizer (AP). Higher pressures and AP contents as well as smaller AP particle size were found to promote sustained combustion and to increase burning rate. The addition of aluminum powder (Al) as a metallic fuel and copper chromite (CC), burning rate accelerator, caused an increase in the burning rate. A significant increase of burning rate was recorded when CC added to the aluminized formulations compared with the non-aluminized of the same oxidizer solid loading and particle size. | ||||
