EFFECTS OF INITIAL BULK TEMPERATURES ON A PROPELLANT'S PRESSURE-COUPLED RESPONSE

RESUMO

The relationship between the burning rate, temperature sensitivity, and initial bulk temperature to a propellant's pressure-coupled response are explored in this paper. A parametric analysis is performed using the Zeldovich−Novozhilov method to illuminate the linkage between a propellant's initial temperature and its resulting pressure-coupled response. Previous testing of an ammonium perchlorate/hydroxyl-terminated polybutadiene propellant in a temperature conditioned T-burner by the author has shown a direct link between a propellant's initial temperature and its pressure-coupled response. The results from this parametric analysis are compared with these data takenby a temperature-conditioned T-burner. This investigation of this linkage between the initial temperature and pressure-coupled response will show that of all the input parameters, the temperature-sensitivity parameter has the largest effect on the pressure-coupled response.
