PPG+AP composite propellants have exhibited extinction behavior when the chamber pressure is increased to some value, Pext, extinction pressure. The extinction pressures were found to be 1) independent of the pressurization rates, 2) altered by addition of carbon powder and 3) diminished by using propellants with higher PPG ratios. By thermal analysis of the propellants used and microscopic observation of the extinguished surfaces it is presumed that these phenomena are due to the differences in decomposition rates between PPG and AP at various chamber pressures and their decomposition enhancement by carbon addition.
