Experiments conducted to characterize wall heat flux for a gas/gas uni-element rocket chamber are presented and discussed. The work was conducted as part of a longer term NASA funded effort titled, 'Focused Validation Data for Full Flow Staged Combustion Injectors.' Full-flow staged-combustion (FFSC) cycle engines were recently considered for use as part of the NASA Reusable Launch Vehicle (RLV). In the FFSC cycle, oxidizer-rich gases drive the oxidizer turbopump and fuel-rich gases drive the fuel turbopump. Both propellants are then injected into the main combustion chamber as gases. The benefits that accompany the FFSC cycle are simplicity and increased thrust to weight ratio relative to other closed cycles. However, experience with gas/gas injectors is limited and, therefore, fundamental studies under uni-element conditions are necessary to understand the important physical/chemical mechanisms and to provide benchmark quality data for CFD code validation and verification.
