Combustion Instability of Solid Propellents: Effects on CTPB Propellent of Oxidizer/Fuel Ratio and Addition of Ferric Oxide (Fe2O3)

reportActive / Technical Report | Accession Number: AD0399784 | Open PDF

Abstract:

The effects of compositional changes on the stability of combustion of a composite propellent based on ammonium perchlorate and carboxy-terminated polybutadiene CTPB have been investigated. A 50.8 mm diameter T-burner was used to study the stability in the frequency range 0.7 to 4.0 kHz at a mean pressure of 6.894 MNsq m 1000 psig. Ferric oxide has a small destabilizing effect on the combustion of CTPB propellents, whereas changes in the oxidizer fuel ratio have a more complex effect. When simple propellent mixes of CTPB rubberammonium perchlorate and polyisobutene PIBammonium perchlorate are compared, the propellent based upon CTPB rubber as fuel appears to be relatively more stable.
