To investigate internal combustion wave rotor technology which improved performance of gas turbine engine

the thermodynamic cycle analysis model of an internal combustion wave rotor gas turbine engine was established.When the parameters of exit Mach number of the internal combustion wave rotor channel and compressor pressure ratio were changed

their influence on the performance of the internal combustion wave rotor gas turbine engine was investigated

and the variable disciplinarian of thermodynamic cycle parameter of the internal combustion wave rotor was discussed.When the compressor pressure ratio equals 3.6

the specific cycle thrust and thermal efficiency increases by up to 23.709%

and the specific fuel consumption decreases by up to 19.165%.When the exit Mach number of the internal combustion wave rotor channel equals 0.6

the specific cycle thrust and thermal efficiency increase by up to 23.736%

the corresponding compressor pressure ratio equals 4.4 at the same time

the thermal efficiency improves 32.216%

specific fuel consumption decreases by 24.366% and entropy generation decreases by 7.864%.It is validated that the technology of the internal combustion wave rotor can enhance the performance of gas turbine engine.The results can provide theory and practice for lucubrating the key technology of the internal combustion wave rotor gas turbine engine.
