Abstract:
To meet the requirements of the main rocket engine of RBCC propulsion system for GO2/kerosene thrust chamber, an investigation of the thrust chamber with work condition changed at a large range and in high combustion pressure and high temperature was conducted. The centre of the thrust chamber injector was one injecting element with inside gas and liquid propellant mixing. The periphery of the thrust chamber injector was spray injecting elements. The important technologies included the ignition of GO2/kerosene propellant, mixing and atomizing of propellant, design of the injector, cooling of its body, design of start, and combustion of two phase stable flow. The results of the investigation show that combustion of the thrust chamber is steady when the chamber pressure changes from 3MPa to 5MPa. The design of the thrust chamber is successful and the thrust chamber works well
