Acoustic mode combustion instability has long plagued the solid propellant industry, and the increasingly frequent requirement for reduced smoke propellants, with concommitant removal of metals from the propellant formulations and, thus, removal of metal oxide particulate products, which have a major role in damping of acoustic oscillations is expected to exacerbate this problem. One strategy for alleviating the problem involves identification and utilization of approaches to decreasing a major source of acoustic energy, namely, the transient burning rate response of the solid propellant to pressure andor crossflow velocity oscillations. Previous preliminary modeling studies have indicated that it might be possible to decrease the pressure coupled response functions of composite propellants by suitable modification of the relative activation energies of the fuel and oxidizer ablation processes.
