Macrokinetic calculation of the ignition of a solid-fuel charge of glycidyl azide polymer in the mini-engine of a microelectromechanical system

The process of ignition of the solid fuel from glycidyl azide polymer in the mini-engine of a microelectromechanical system has been considered. Macrokinetic calculations of the self-ignition temperature of the fuel and the induction period for different heat transfer conditions have been made. On the basis of the critical thermal flux determination, recommendations on the choice of the minimum power and size of the thermistor in the igniter of the solid-fuel mini-engine have been formulated.
