- In our previous investigation, we measured the global temperature sensitivity coefficient of a deterred spherical single base gun propellant following an experimental procedure that did not allows us to determine the local temperature sensitivity coefficients of the deterred and undeterred parts of the investigated propellant. In this paper, we propose an experimental methodology to measure the local temperature sensitivity coefficients of both parts of the spherical deterred gun propellant. This methodology can be summarized as follows: Firstly, we separated the ranges of pressure where the combustion of the deterred and the undeterred parts of the spherical propellant occurs by means of infrared (IR) microscopy measurements. Then the burning rate of the propellant as a function of pressure was calculated according to STANAG 4115 at different initial temperatures. Finally, we determined the local temperature sensitivity coefficients of each part of the spherical propellant.
