RESEARCH ON COMBUSTION OF SOLID PROPELLANTS
Abstract
A study was made to relate theoretically predicted and experimentally observed pressure-coupled combustion instability behavior of solid propellants. Using a generalized theoretical model which incorporates both surface and gas phase combustion effects, the linear and nonlinear (higher pressure amplitude) region has been characterized by a group of combustion parameters. Concurrent experimental studies were directed toward investigating (1) the effects of coating the solid oxidizer crystals, (2) the chemical and physical nature of the propellant binder, catalysts, and crosslinking agents on the acoustic admittance, (3) nonlinear response properties, and (4) propellant burning rate. The data show that small changes in propellant formulations can have a significant effect on the derived parameters characterizing the surface and, therefore, on relative contributions of these reactions to the acoustical response properties.
