Nonlinear Burning Stability of Solid Propellants.

Abstract

The nonlinear burning analysis of solid rocket propellants, under development by this research group, was extended to include in particular variable thermal properties and volumetrically distributed chemical reactions in the condensed phase. The theory is restricted to monodimensional combustion waves and thin (i.e., quasi-steady gas phase) heterogeneous flames of thermal nature. Bifurcation diagrams were obtained, predicting the existence of: time-independent steady burning, self-sustained oscillatory steady burning, no steady sustained burning. Several bifurcation parameters were recognized. Static stability boundaries, dynamic stability boundaries, static burning boundaries, pressure deflagration limits were determined for unmetallized AP-based composite propellants. Several thin flame models, available from literature, were properly modified and extended.
