Lifted flame combustion promotes more complete and controlled mixing of fuel and oxidizer before ignition, reducing aircraft emissions and enabling more sustainable fuel burn. In this research conducted at the Ben T. Zinn Combustion Laboratory, a 900°F, 30-bar high-pressure combustion rig was designed to facilitate jet-in-crossflow lifted flame combustion. The rig incorporates bilayer ceramic components with metal liners across key sections, including the ignitor, vitiator, flow transition, test, and exhaust assemblies. The design process accounted for thermal growth, fitment tolerances, optical access for imaging, and multiple configuration iterations to enable a dynamic testing setup. A ceramic casting study was performed to characterize the shrinkage of Cotronics ceramic components during curing, providing data to refine mechanical design tolerances. Additionally, computational fluid dynamics (CFD) analyses using ANSYS Fluent were conducted to investigate downstream swirl effects induced by the vitiator. The completed rig design and initial component fabrication advanced the understanding of lifted flame dynamics and their role in reducing combustion emissions for more sustainable flight.
