Abstract:
A gas turbine engine comprising:at least one gas generator and a power turbine arranged to drive a propulsion output shaft, said gas generator including coupled gas compressors and turbines;said gas generator generating a first stream of high pressure gas at a high temperature high pressure and a second stream of low pressure gas at a low temperature; anda wave rotor convertor between said gas generator and said power turbine receiving said first and second streams of gas from said gas generator, said wave rotor combining said first and second streams of gas into a third stream of high pressure gas of an intermediate temperature intermediate the temperatures of said first and second streams of gas;said third stream of gas being directed from said wave rotor convertor to said power turbine for driving said power turbine and propulsion output shaft.
