- Theoretical studies are presented on the time-independent and oscillatory combustion of nonmetallized AP/composite propellants. Three hypotheses are introduced: (1) The extent of propellant degradation at the vaporization step has to be specified through a scientific criterion. (2) The condensed phase degradation reaction of ammonium perchlorate to a vaporizable state is the overall rate-limiting step. (3) Gas phase combustion rate is controlled by the mixing rate of fuel and oxidizer vapors. In the treatment of oscillatory combustion, the assumption of quasi-steady fluctuations in the gas phase is used to supplement these hypotheses. In comparison with experimental data, this study predicts several of the observations including a few that remain inconsistent with theoretical results.
