Abstract
A turbine guide blade includes a platform which absorbs thermal loads and a fastening region adjoining the platform for absorbing mechanical loads. The fastening region has such a slim construction that it leaves a cold side of the platform readily accessible.
Claims17
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 along 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 along 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;
- and
- 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.
