The purpose of present work is to clarify the mechanisms of the electrostatic field influence on the polymers (PMMA) combustion in high enthalpy flows. For this, the PMMA temperature profiles during combustion in a hybrid rocket engine studies were carried out. Based on the results obtained the assumption about the intensification of the substance...

... shape of the curve at U = 0 kV is in qualitative agreement with the data of [4]. According to [5], the PMMA thermal decomposition start temperature is in the range 0 C. The Fig. 1 contains inhomogeneities are observed in this temperature range, which arise due to thermocouple junction contact with the gas bubbles in the subsurface of the polymer. It was not possible to determine the exact value of the temperature at which the thermocouple exits to the surface, however, in the literature [4][5], the possible ...
