Abstract

Physical Sciences Inc. proposes to design, develop, and demonstrate an experimental apparatus that will characterize in-chamber processes of Al-Al_2O_3 particle evolution and dynamic behavior under various pressure, temperature, and critical flow field conditions, of large solid rocket motors. We have proposed to maximize particle characterization to ensure a thorough and systematic understanding of Al-Al_2O_3 droplet evolution and dynamic behavior, from particle creation at the propellant surface to the nozzle throat using a combination of diagnostic measurements. Our approach will ensure reliable and relevant experimental data of Al-Al_2O_3 particle dynamic evolution in SRMs for the development of robust and accurate physics based performance prediction codes. BENEFIT: It is anticipated that reliable and relevant experimental data of Al-Al_2O_3 particle evolution and collision dependent dynamic behavior in SRM environments will ensure successful development of robust and accurate physics based performance prediction codes. Integration of such physics based droplet models into the state-of-the-art simulation tools will enhance prediction capability of our motor systems during the design stage and ensure larger performance gains in weapon systems. This capability will benefit all critical US weapon development programs.
