Research on the Deflagration of High-Energy Solid Oxidizers
Abstract
Measurements of the flame temperature of deflagrating hydrazine diperchlorate using fine Chromel-Alumel thermocouples have been completed at 28 atm. A value of 1385 + or -35 deg K (corrected for radiation heat loss of the thermocouple) was obtained. Experiments at 55 atm have tentatively put the flame temperature at above 1500 deg K at this pressure. Both temperatures are below the theoretical value of 1600 deg K and indicate that thermodynamic equilibrium is not attained in the flame, although it may be at higher pressures. The temperature profile through the combustion wave was obtained for deflagration at 28 atm. No indication of heat release up to 190 deg C (the melting point of HDP) in the condensed heated zone of the oxidizer was observed. The thickness of the preheat zone was measured as 550 + or -80 microns, and the thermal diffusivity was determined to be 0.0015 + or -.0005 sq cm/sec, for HDP of 2.1 g/cc density.
