The mechanism of burning rate catalysis in composite HTPB-AP propellant combustion
Journal Article

· Combust. Flame; (United States)
Evidence has been presented in this study that binder thermal degradation is rate limiting at low pressures (2-7 MPa) in HTPB/AP propellant combustion when catalyzed by copper chromite, Cr(Salen-N-decyl)/sub 3/, and copper phthalocyanine. The condensed phase chemistry governing binder degradation is probably associated with breaking of the urethane linkages. The weak link degradation mechanism would allow formation of liquid or molten binder phases on the propellant surface. At higher pressures (8-14 MPa), the burning rate appears to be increasingly controlled by gas diffusion processes.
