Thermal Safety Study of One New-Type DB Propellant

Abstract:

The thermal safety of one new-type DB propellant SZQu-1 was studied by ARC. The test results were compared with the one of double-base propellant SF-3. The ARC test results show that, in an ideal adiabatic environment, the initial exothermic temperature for SZQu-1 is 129.0°C, the adiabatic temperature rise is 787.0°C, the maximum self-heating rate is 23329.9°C/min, the maximum pressure rise rate is 51.2×10⁵Pa·min^-1, and the maximum pressure produced by unit mass is 124.1×10⁵Pa·g^-1. The activation energy E is 212.2kJ·mol^-1, the frequency factor A is 1.3×10²²s^-1, and T_D24 is 123.0°C, which are calculated by the velocity constant method. The studies have revealed that, comparing with SF-3, SZQu-1 has worse thermal stability and stronger explosiveness.
