Abstract
Proposed is a turbine blade seal assembly structure including a turbine blade comprising an airfoil part, a platform part, and a root part, a turbine rotor disk allowing the root part of the turbine blade to be mounted thereto and having a mounting rib extending radially from one axial side of the turbine rotor disk to form a mounting groove, a retainer plate mounted between the platform part and one side part of the turbine rotor disk so as to seal a cooling flow path formed inside the root part and the platform part, and an insert key inserted axially into an upper end of the mounting rib and inserted into a lower end of the retainer plate to support the retainer plate.

A turbine blade seal assembly structure comprising:
- a turbine blade comprising an airfoil part, a platform part, and a root part;
- a turbine rotor disk allowing the root part of the turbine blade to be mounted thereto and having a mounting rib extending radially from one axial side of the turbine rotor disk to form a mounting groove;
- a retainer plate mounted between the platform part and one side part of the turbine rotor disk so as to seal a cooling flow path formed inside the root part and the platform part;
- and
- an insert key inserted axially into an upper end of the mounting rib and inserted into a lower end of the retainer plate to support the retainer plate.
A gas turbine comprising:
- a compressor configured to suck in and compress outside air;
- a combustor configured to mix fuel with air compressed in the compressor and combust the fuel;
- and
- a turbine rotated by combustion gas discharged from the combustor,
- wherein the turbine comprises:
- a turbine blade comprising an airfoil part, a platform part, and a root part;
- a turbine rotor disk allowing the root part of the turbine blade to be mounted thereto and having a mounting rib extending radially from one axial side of the turbine rotor disk to form a mounting groove;
- a retainer plate mounted between the platform part and one side part of the turbine rotor disk so as to seal a cooling flow path formed inside the root part and the platform part;
- and
- an insert key inserted axially into an upper end of the mounting rib and inserted into a lower end of the retainer plate to support the retainer plate.
