Burning of Solid Propellant in Gas Generator of an Air-Breathing Engine at Large Content of Metal

Abstract

The features of burning of solid propellant with a high metal content (over 40%) under conditions of a separately located gas generator of an air-jet engine were investigated. It was shown that solid propellant with a high metal content burns in the mode of dominant heat release in the condensed phase. It was found that metal propellant under conditions of the condensed phase is not a simple heat sink, but plays an active role in burning. The oxidation of the metal under the conditions of the condensed phase maintains the thermal balance of the condensed phase during burning of solid propellant.
