Abstract

Provided is a gas turbine system including: a compressor that compresses external air to generate compressed air; a combustor that burns the compressed air generated by the compressor together with fuel to generate a combustion gas; a turbine driven by the combustion gas generated by the combustor; an exhaust unit that guides a combustion gas that has passed through the turbine to outside; a nacelle formed in a cylindrical shape and extending along an axis line about which the turbine rotates and arranged so as to cover the compressor, the combustor, the turbine, and the exhaust unit; and an exit unit that guides the combustion gas, which passed through the turbine, to a discharge port provided in the surface of the nacelle.

First claim

1 . A gas turbine system comprising:
a compressor that compresses external air to generate compressed air; a combustor that burns the compressed air generated by the compressor together with fuel to generate a combustion gas; a turbine driven by the combustion gas generated by the combustor; an exhaust unit that guides a combustion gas that passed through the turbine to outside; a shell formed in a cylindrical shape and extending along an axis line about which the turbine rotates and arranged so as to cover the compressor, the combustor, the turbine, and the exhaust unit; a heat exchange unit that exchanges heat between the combustion gas that passed through the turbine and external air flowing on a surface of the shell, the heat exchange unit exchanging heat between a combustion gas and external air by guiding, to at least one discharge port provided in a surface of the shell, a combustion gas that passed through the turbine and mixing the combustion gas with external air; and an introduction unit that guides the mixed gas, in which the combustion gas discharged from the discharge port and external air are mixed, to the exhaust unit from at least one introduction port provided in the surface of the shell, wherein discharge ports each comprising the discharge port are provided to a plurality of portions in a circumferential direction about the axis line, wherein introduction ports each comprising the introduction port are provided to a plurality of portions in the circumferential direction, and wherein the discharge ports and the introduction ports are arranged at positions overlapping each other in the circumferential direction.

2 - 4 . (canceled)

5 . The gas turbine system according to claim 1 further comprising at least one channel forming portion that covers the discharge port and the introduction port and forms a mixed gas channel through which the mixed gas flows between the channel forming portion and the surface of the shell.

6 . The gas turbine system according to claim 5 ,
wherein the channel forming portion extends along the axis line and is formed in a cylindrical shape about the axis line, and wherein the mixed gas channel is a channel formed annularly about the axis line.

7 . The gas turbine system according to claim 5 , wherein channel forming portions each comprising the channel forming portion extend along the axis line and are spaced apart in a plurality of portions in the circumferential direction so as to cover both the discharge port and the introduction port.

8 . The gas turbine system according to claim 1 further comprising a generator coupled to the turbine and configured to generate electric power by driving of the turbine and supply electric power to a thrust generator that generates thrust from electric power.

9 . A moving body comprising:
the gas turbine system according to claim 8 ; and a thrust generator that generates thrust from electric power generated by the gas turbine system.
