Effect Of Unsteady Combustion On The Stability Of Rocket Engines, Tina Morina Rice
Effect Of Unsteady Combustion On The Stability Of Rocket Engines, Tina Morina Rice
Doctoral Dissertations
Combustion instability is a problem that has plagued the development of rocket-propelled devices since their conception. It is characterized by the occurrence of high-frequency nonlinear gas oscillations inside the combustion chamber. This phenomenon degrades system performance and can result in damage to both structure and instrumentation.
The goal of this dissertation is to clarify the role of unsteady combustion in the combustor instability problem by providing the first quantified estimates of its effect upon the stability of liquid rocket engines. The combination of this research with a new system energy balance method, accounting for all dynamic interactions within a system, …
