Gas turbine engine with recuperator

A gas turbine engine comprising a can-type combustor, a compressor wheel for supplying compressed air to the can-type combustor, a turbine wheel driven by a combustion gas generated in the can-type combustor for driving the compressor wheel, and a circular plate-type heat exchanger for conducting a heat exchange between the combustion gas discharged from the turbine wheel and the compressed air supplied to the can-type combustor, wherein said compressor wheel, said turbine wheel, said can-type combustor and said plate-type heat exchanger are disposed coaxially;

• said plate-type heat exchanger is disposed at a location radially outside said can-type combustor and axially offset from said compressor wheel and said turbine wheel;
• and a compressed-air passage for guiding the compressed air from said compressor wheel to said plate-type heat exchanger and a combustion gas passage for guiding the combustion gas from said turbine wheel to said plate-type heat exchanger are disposed radially outside said compressor wheel and said turbine wheel.
