A turbine vane having an airfoil part and platform parts integrally formed respectively on opposite radial ends of the airfoil part, the turbine vane comprising:
- a plurality of segments divided in a circumferential direction, and
- a sealing assembly inserted into slots formed in opposing sides of platform parts of two segments,
- wherein the sealing assembly comprises:
- a first sealing member mounted at a predetermined angle with respect to the circumferential direction,
- a second sealing member coupled to the first sealing member and bent to have a curved surface in the circumferential direction, and
- a third sealing member which is axially replaceably inserted into each of the slots and is elastically supported and secured by the second sealing member.
A turbine having turbine blades and turbine vanes mounted therein, with the turbine blades being rotated by combustion gas discharged from a combustor, wherein each of the turbine vanes comprises an airfoil part and platform parts integrally formed respectively on opposite radial ends of the airfoil part;
- consists of a plurality of segments divided in a circumferential direction;
- and
- comprises a sealing assembly inserted into slots formed in opposing sides of platform parts of two segments,
- wherein the sealing assembly comprises:
- a first sealing member mounted at a predetermined angle with respect to the circumferential direction,
- a second sealing member coupled to the first sealing member and bent to have a curved surface in the circumferential direction, and
- a third sealing member which is axially replaceably inserted into each of the slots and is elastically supported and secured by the second sealing member.
A turbomachine comprising:
- a compressor configured to suck and compress external air;
- a combustor configured to mix fuel with air compressed in the compressor and combust a mixture of the fuel and the compressed air;
- and
- a turbine having turbine blades and turbine vanes mounted therein, the turbine blades being rotated by combustion gas discharged from the combustor,
- wherein each of the turbine vanes comprises an airfoil part and platform parts integrally formed respectively on opposite radial ends of the airfoil part;
- consists of a plurality of segments divided in a circumferential direction;
- and
- comprises a sealing assembly inserted into slots formed in opposing sides of platform parts of two segments,
- wherein the sealing assembly comprises:
- a first sealing member mounted at a predetermined angle with respect to the circumferential direction,
- a second sealing member coupled to the first sealing member and bent to have a curved surface in the circumferential direction, and
- a third sealing member which is axially replaceably inserted into each of the slots and is elastically supported and secured by the second sealing member.
