Regarding the Influence of High Frequency Combustion Instabilities on Operation of Solid Rocket Motors
Journal Title: Problemy Mechatroniki. Uzbrojenie, lotnictwo, inżynieria bezpieczeństwa - Year 2011, Vol 2, Issue 1
Abstract
High frequency combustion instabilities imply a major risk for the solid rocket motor’s stable operation and they are directly linked to the response of the solid propellant to the pressure coupling. Our paper aims at defining a linearized one-dimensional flow study model of the solid propellant rocket motors’ disturbed functioning analysis. Experimental researches were done with an adequate setup, built and improved in our lab, functioning on the basis of the nozzle throat intermittent modulating technique developed by ONERA researchers, able to evaluate the propellant response by the interpretation of the pressure oscillations damping in terms of propellant response.
