Abstract: Turbine-based combined cycle has attracted widespread attention in the global research institutions because of its superior performance. In order to simulate the TBCC test conditions, it is necessary to provide the qualified high temperature gas. A simple and easy control simulation model of TBCC core jet was designed and experimentally studied. The results indicate that the model can provide reliable ignition, high combustion efficiency, and high temperature gas of 0.236~0.342kg/s from 750~1050K.The uniform distribution of outlet Mach number, temperature and oxygen volume fraction could meet the requirements of TBCC super combustion chamber test. The results provide strong technical support for the design and study of the core components of the TBCC combustion chamber mixer and flame stabilizer. 

Key words: Turbine-based combined cycle；Core jet；Combustion efficiency；Equivalence ratio
