[57] ABSTRACT

A gas turbine engine E includes a compressor Wheel 9 and

a turbine Wheel 10 ?xed to a rotary shaft 8, a can-type

combustor 18 disposed on an extension of the axis L of the rotary shaft 8, and an circular plate-type heat exchanger 12

disposedtosurroundaradiallyouterportionofthecan-type

combustor 18. The compressor Wheel 9, the turbine Wheel 10, the can-type combustor 18 and the plate-type heat

exchanger12aredisposedcoaxianyWiththeaxisLofthe

rotaryshaft8.Therefore,the?oWsofcompressedairand Combustion gas are symmetrized With respect to the axis L, and the distribution of temperature Within a Casing is also symmetriZed With respect to the axis L. Thus, the ?oWs of compressed air and combustion gas Within the gas turbine engine E can be axially symmetriZed, and the generation of a thermal distortion can be prevented.
