Abstract

Abstract : Various modifications to the monopropellant solid oxidizer ammonium perchlorate are described. Cation replacement, or 'doping' of AP by Sr(++) ion and deuteration to provide ND4ClO4 did not alter the burning rate from that of pure NH4ClO4 at 14.7 psia. Hydrated aluminum sulfate shows an ability to extinguish AP combustion at the 5% level, whereas 2% does not even alter the burning rate at atmospheric pressure. The theoretical adiabatic combustion species for AP and dihydroxy glyoxime (DHG) at 1, 34 and 68 atmospheres are given. DHG produces fuel rich rather than oxygen rich monopropellant combustion species.
