Focused Rbcc Experiments: Two-Rocket Configuration Experiments and Hydrocarbon/Oxygen Rocket Ejector Experiments

Description
This addendum report documents the results of two additional efforts for the Rocket Based Combined Cycle (RBCC) rocket-ejector mode research work carried out at the Penn State Propulsion Engineering Research Center in support of NASA s technology development efforts for enabling 3 d generation Reusable Launch Vehicles (RLV). The tasks reported here build on an earlier NASA MSFC funded research program on rocket ejector investigations. The first task investigated the improvements of a gaseous hydrogen/oxygen twin thruster RBCC rocket ejector system over a single rocket system. The second task investigated the performance of a hydrocarbon (liquid JP-7)/gaseous oxygen single thruster rocket-ejector system. To gain a systematic understanding of the rocket-ejector s internal fluid mechanic/combustion phenomena, experiments were conducted with both direct-connect and sea-level static diffusion and afterburning (DAB) configurations for a range of rocket operating conditions. For all experimental conditions, overall system performance was obtained through global measurements of wall static pressure profiles, heat flux profiles and engine thrust. Detailed mixing and combustion information was obtained through Raman spectroscopy measurements of major species (gaseous oxygen, hydrogen, nitrogen and water vapor) for the gaseous hydrogen/oxygen rocket ejector experiments.Santoro, Robert J. and Pal, SibtoshMarshall Space Flight CenterCOMBUSTION PHYSICS; EJECTORS; HYDROGEN OXYGEN ENGINES; ROCKET-BASED COMBINED-CYCLE ENGINES; SPACECRAFT CONFIGURATIONS; HYDROCARBON FUELS; COMPUTATIONAL FLUID DYNAMICS; HEAT FLUX; RAMAN SPECTROSCOPY; PRESSURE DISTRIBUTION; SPACECRAFT PROPULSION; THRUST; AFTERBURNING; DIFFUSION...
