Abstract
Abstract A gas turbine engine E includes a compressor wheel 9 and a turbine wheel 10 fixed 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 disposed to surround a radially outer portion of the can-type combustor 18. The compressor wheel 9, the turbine wheel 10, the can-type combustor 18 and the plate-type heat exchanger 12 are disposed coaxially with the axis L of the rotary shaft 8. Therefore, the flows of compressed air and 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 flows 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.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
157 words
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.
Claim 2
Dependent Claim
157 words
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.
