Performance Study on Turbofan Engine with Turbine Inter Burner

Based on the thermodynamics model of two-spool,mixed-flow turbofan engine,the design point performance of turbofan engine with turbine inter-blade burner(TIB) was calculated and analyzed by the parameter analysis of the air thermodynamics cycle.The effect of the TIB on the engine altitude,velocity and rotational speed,was studied and compared with conventional turbofan.The calculation results show that introducing the TIB,the specific thrust is obviously increased while the specific fuel consumption only increase appreciably,and the engine performance is improved.
