Research on Titanium-Containing Micro-Porous Propellants with Rapid Burning Rate
Micro-porous propellants containing titanium powder were obtained by supercritical CO2 (SC CO2) foaming technique. The morphologies of the micro-porous propellants were characterized by scanning electron microscopy (SEM) and energy-dispersive X-ray spectroscopy (EDS) measurement. The burning rate, the impetus, and the heat of explosion of the micro-porous propellants were measured by the closed vessel test and the calorimetric bomb test. The results show that the porosity increased with increasing titanium powder content; compared with Benite, the burning rate was substantially improved, and the maximum values of the impetus and the isochoric heat of explosion increased by 51.4% and 6.5%, respectively. The Ti-containing micro-porous propellants with rapid burning rate and better energetic properties described in this paper may have the potential to replace Benite as igniter material in a flame igniter of a gun propellant charge.
