Combustion Study of Composite Solid Propellants Containing Metal Phthalocyanines
TLDR
In this article, the effect of transition metal Phthalocyanines on the burn rate of composite solid propellants was investigated, as well as the combustion characteristics of such propellants.Abstract:
Transition metal Phthalocyanines have been used as burn rate modifiers for AP-HTPB composite solid propellants. An effort has been made to investigate the effect of Cu-Co-and Fe Phthalocyanines on the burn rate of composite propellants, as also on the combustion characteristics of such propellants. The burn rate has been determined in Crawford Strand Burner at 56 kg/cm 2 pressure as also in low pressure burner setup at vacuum of 0.5 kg/cm 2 . Thermal analysis was performed using Thermo Gravimetric Analyzer (TGA), Differential Scanning Calorimeter (DSC) and heat of reaction has been measured by conventional Bomb Calorimeter. Scanning Electron Microscope (SEM) and Elemental Analyzer have been used for material characterization and possible composition of composite solid propellants. Metal Phthalocyanines have been found to influence the decomposition and to enhance the burn rate of the composite solid propellants.read more
