Definitions
- the present invention relates to a gas turbine cooling blade, and more particularly, to a gas turbine cooling blade configured to reduce thermal stress between a blade base and a platform.
- the gas turbine bin cooling blade according to the present invention has a cooling air flow path inside, and is attached to a platform arranged around the mouth and the gas turbine bin cooling blade.
- An elliptical wing surface formed around the base of the rotor blade in contact with the platform; and a wing portion of a linear portion formed to have a predetermined length continuously from the elliptical wing surface.
- a curved wing surface extending to the tip with a predetermined curved surface continuing from the straight portion wing surface.
- the wing surface which was conventionally a curved surface, becomes a straight line portion, that is, the arc-shaped portion, which has a conventionally inwardly convex shape, becomes a straight line.
- the wing has a larger cross-sectional area than conventional ones. Therefore, the heat capacity of the blade according to the present invention is also larger than the heat capacity of the conventional blade, and the temperature difference from the platform becomes smaller as the heat capacity of the blade increases.
