Abstract
A combustor (14) is placed next to a turbine (16), on the side opposite a compressor (12). A heat insulation device (20) for reducing the transmission of heat from the high-temperature side to the low-temperature side is provided between the combustor/turbine and the compressor. A connection shaft (18) has an axial hole (18a) open on the inlet side of the compressor and axially extending to near a turbine impeller, and also has a radial hole (18b) open near the turbine impeller to the outside of the connection shaft and radially extending to be in communication with the axial hole.
Claims6
A gas turbine engine including a compressor for compressing air, a combustor for burning a fuel in pressurized air compressed by the compressor to generate hot gas, and a turbine rotated by the hot gas, wherein
- the combustor is installed adjacent to the turbine opposite to the compressor, and
- a heat insulation device is installed between the combustor/turbine and the compressor to reduce conduction of heat from a high-temperature side to a low-temperature side.
A gas turbine engine including a compressor for compressing air, a combustor for burning a fuel in pressurized air compressed by the compressor to generate hot gas, and a turbine rotated by the hot gas, wherein
- a compressor impeller of the compressor is connected to a turbine impeller of the turbine via a connection shaft, and
- the connection shaft is provided with an axial hole opened towards an inlet side of the compressor and axially extending to the vicinity of the turbine impeller, and a radial hole opened towards the outside of the connection shaft adjacent to the turbine impeller and radially extending, the radial hole being in communication with the axial hole.
A gas turbine engine including a compressor for compressing air, a combustor for burning a fuel in pressurized air compressed by the compressor to generate hot gas, and a turbine rotated by the hot gas, the gas turbine engine comprising:
- a gas guide plate, interposed between the combustor and the turbine, for guiding the hot gas to the turbine, the gas guide plate including a radiation fin for preheating the pressurized air.
