Abstract
The rate of negative erosive combustion is calculated using analytical methods and a simple model of the gas-phase chemical reactions A → B. The conversion of part of the thermal energy into the kinetic energy of motion of gaseous combustion products along the propellant gasification surface is taken into account within the model. Solutions are obtained for the cases where the thickness of the laminar sublayer is larger or smaller than the width of the combustion zone in the gas phase. The calculation results confirm the author’s previous conclusion: manifestation reduction in the negative erosive effect with decreasing initial temperature of the propellant is caused by narrowing of the region of its occurrence.
