DEVELOPMENT OF HIGH TEMPERATURE-RESISTANT PROPELLANTS

Abstract

Propellants with silicone and fluorocarbon binders possessed superior heat resistance to the synthetic rubbers, but lacked energy. Carbon black and powdered aluminum were added to these propellants to boost the impetus, but without success. A slight improvement was noted only with aluminum in a fluorocarbon. Potassium nitrate was investigated as a chlorine-free inorganic heat-resistance oxidizer in a synthetic rubber binder, but none of the compositions would ignite. TE ADDITION OF POWDERED ALUMINUM AND BORON DID NOT AID COMBUSTION. Cyclotetramethylene tetranitramine (HMX) was found to have promise as an organic heat resistant oxidizer in a synthetic rubber binder where it gave greater impetus than potassium perchlorate; however, burning rate was considerably slower. None of the HMX propellants exhibited enough heat resistance to meet the 400 F objective, but one composition, HES-6616, showed potential 300 to 350 F resistance.
