Research on Solid Propellant Combustion Instability

Abstract

A fundamental study of the non-steady combustion of solid propellants with application to rocket instability is described. A film strip of a metallized solid propellant burning in an oscillating pressure field was analyzed in order to determine the phase relationship between the imposed pressure maxima and an apparent wave of luminosity in the combustion gases. The implications of these observations as they affect the model of the burning propellant are briefly considered. Two types of experimental observation which will be used to study non-steady combustion are outlined. One method involves the measurement of the temperature of the combustion gases downstream from the flame zone. The use of a particle track method for the observation of pressure- velocity relationships in the burnt gases is also considered.
