A Unified Theory of Solid Propellant Ignition. Part 3. Computer Solutions

Abstract

Computer solutions are obtained for several ignition models involving either surface or gaseous exothermic chemistry. Surface regression and convection of products from the surface are found to be limiting for the surface reaction of gaseous oxidizer and solid fuel. Fast gas phase reactions cannot in general be distinguished from surface and solid phase reactions by the experimental determination of the dependence of ignition time on igniting flux; a more usable technique may be the effect of concentration on ignition regimes. Slow gas phase reactions would be best studied by photographic observation of the developing gaseous reaction zone. Further analyses, coupled with judiciously chosen numerical solutions, offer a reasonable path to the solution of the remaining unresolved questions.
