Active Control of Pressure Oscillations in Liquid-Fueled Propulsion Systems

Abstract

This program has been devoted to analytical work motivated and guided by experimental results obtained largely by other organizations. The three primary research objectives are representation of linear and nonlinear combustion instabilities, encompassing all contributions to energy gains and losses, including noise sources, in a form suitable for application of active control; modeling unsteady combustion processes and their coupling to unsteady flow fields; and application of control theory, analysis, and design to combustion chambers, with particular attention to robustness in the presence of uncertain variations of parameters. Although not addressed in the past two years, eventually application of methods of nonlinear control will be investigated.
