Abstract:

The temperature sensitivity of JA2 7 perf propellant was studied by conditioning it to 21.1 deg C, 48.9 deg C, and -31.7 deg C. The firings were conducted in a 120-cc closed chamber, conventionally and with plasma injection ETC, using a 1.2-ms pulse width provided by four banks of a 400 kJ PFN Pulse Forming Network. The study showed a decrease in the burn rate between the ETC firings at 21.1 deg C and the conventional at the same temperature, but it showed an increase in the burn rate for the 48.9 deg C and -31.7 deg C cases, respectively.
