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

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 MN/sq 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 rubber/ammonium perchlorate and polyisobutene (PIB)/ammonium perchlorate are compared, the propellent based upon CTPB rubber as fuel appears to be relatively more stable.
