STUDY ON COMBUSTION OF LIQUID AND GELATINIZED GLYCIDYL AZIDE OLIGOMERS

摘要

Effect of the molecular weight of glycidyl azide oligomers on the burning rate and effect of gelatinization have been examined. It has been shown that combustion of uncured GAP obeys usual rules of monopropellant burning of liquid energetic materials with all resulting consequences (turbulization, unusual burn rate-pressure dependence, etc.). Small additives of PMMA, used as a gelatinizing agent to GAP oligomers appeared to influence drastically their burning behavior through alteration of the viscosity. Data on combustion ofuncured neat azide oligomers and their compositions with the polymer as well as data of temperature measurements in the combustion wave have been used to propose the combustion mechanism of azide energetic materials.
