Abstract:
A turbine guide blade, comprising:a guide blade axis; a blade profile disposed along said axis, said blade profile having a profile contour; a platform following said blade profile axially along said axis and disposed transversely of said axis, said platform having a hot-gas side for defining a hot-gas duct of a turbine and a cold side opposite said hot-gas side; a fastening region following said platform axially along said axis and disposed transversely of said axis, for absorbing most mechanical loads caused by a working medium flowing around said blade profile; said platform having to absorb at most a small portion of the mechanical loads; said fastening region, in a projected view along said axis in a direction from said fastening region toward said blade profile, covering less than three quarters of said cold side, said fastening region having a core connected to said cold side, said core having a core contour extending co-directionally with said profile contour, and said fastening region further having a planar web extended along said axis, for fastening in a turbine casing; and a horizontal rib interconnecting said core and said planar web, said horizontal rib extending from said core to said planar web in a continuous widening manner and providing a stiffening connection substantially perpendicularly to said axis.
