Experiments to determine the effect of surface area, head space, and containment on liquid gun propellant degradation at temperatures of 100 and 148°C were conducted. The conclusions from these tests are that an increased surface area in LP containment can significantly increase the rate of LP decomposition. The head space is not a significant factor in altering the rate of degradation, but if the gaseous products are allowed to escape, the degradation rate is significantly lowered.
