Abstract
The invention relates to a guide vane (17) for a turbomachine (1), in particular a gas turbine guide vane, in which the platform (48) has a separating region (50), which is embodied as a separate component. This has, in particular, advantages with respect to the simplification of cast blade/vane (17) in terms of manufacturing technology, with respect to the variability of a material selection, the quality of a protective coating to be applied and efficient cooling.
Claims22
A guide blade, for a machine, comprising:
- an aerofoil region;
- a fastening region;
- a platform region, wherein the platform region is designed to accept a separating region, non-destructively separable from the blade, the separating region being part of a platform associated with the platform region, for bounding a flow duct in the machine;
- and
- a stiffening rib, connected from the separating region to the fastening region.
A guide blade, for a machine, comprising:
- an aerofoil region;
- a fastening region;
- a platform region, wherein the platform region is designed to accept a separating region, non-destructively separable from the blade, the separating region being part of a platform associated with the platform region, for bounding a flow duct in the machine;
- and
- an intermediate piece, between the platform region and the separating region, for sealing a gap, remaining after attachment of the separating region and the platform region.
A guide blade, for a machine, comprising:
- an aerofoil region;
- a fastening region;
- and
- a platform region, wherein the platform region is designed to accept a separating region, non-destructively separable from the blade, the separating region being part of a platform associated with the platform region, for bounding a flow duct in the machine, wherein the guide blade is a single crystal guide blade.
A guide blade, for a machine, comprising:
- an aerofoil region;
- a fastening region;
- and
- a platform region, wherein the platform region is designed to accept a separating region, non-destructively separable from the blade, the separating region being part of a platform associated with the platform region, for bounding a flow duct in the machine, wherein the guide blade is directionally solidified.
