This test campaign studied the combustion performance of novel air-hydrogen injectors for the preburner of Reaction Engines SABRE engine. The subscale testing involved providing two air feeds (<1kg/s) and two hydrogen feeds (<5g/s), each of which required closed loop feedback control of massflow. Constant massflow profiles were used to evaluate combustion performance and ramped profiles to evaluate flame blow-off. Instrumentation requirements included standard pressure and temperature measurements, high-speed pressure measurements for combustion oscillations, high speed video and laser imaging for non-intrusive monitoring of the flow field.
