LOW TEMPERATURE BEHAVIOR OF N-5 PROPELLANT

Abstract

The low temperature behavior of several samples of N-5 rocket propellant was studied using DTA. The only significant occurrence during cooling to -100C was the glass transition. The temperature of this transformation was found to be -58F plus or minus 3F by dilatometry. In addition, the variability of tensile strength, elongation, and strength modulus among three producers was examined. Significant variations were found among lots from any one plant; but variations in the average values for each plant were not significant.
