This study analyzed the electrostatic sensitivity energy tendency, ignition cause and minimum ignition energy of solid propellant according to accelerated aging. After a certain period, the internal charging potential of both propellants A and B increased, but no further change occurred. Although the mechanical properties of B are better, other factors should be considered because the ignition probability is higher than A. In the case of B, the temperature influence due to external factors is relatively small because the arrhenius constant is lower than A and the activation energy value is large. also, it was confirmed that the mechanical property value according to aging did not significantly decrease due to high elasticity. Furthermore, since the number of ignitions increased as the internal charging potential increased, calculating this was considered as a method that can confirm the minimum ignition energy.
