Abstract
- The problem of interaction of a thermocouple inserted into a unitary solid propellant with a moving heat wave spreading inside the propellant from the combustion surface is considered. The results of numerical modelling showed that a heat sink directed deep into the propellant occurs along the thermocouple wire because of large differences in the heat conductivity coefficients of the propellant and the thermocouple material, which essentially changes the temperature of the thermocouple junction and hence distorts the indications.
