Definitions
- the present invention relates to a guide vane arrangement of a turbomachine, in particular a gas turbine.
- a typical vane assembly includes at least one vane support attached to a housing of a turbomachine. Such a vane assembly also includes a plurality of vanes mounted on the vane support and circumferentially juxtaposed.
- each vane has a platform having at least two latch portions circumferentially spaced from one another.
- Each latch portion has a tongue which projects circumferentially from the platform and extends in the axial direction.
- the vane support has at least two support portions which are circumferentially spaced from each other.
- Each support portion has a groove which is open in the circumferential direction and extends in the axial direction. The tongues of the locking portions and the grooves of the support portions are so 2 B05 / 049-0
- a vane arrangement of this type provides the ability to assemble and disassemble individual vanes without disassembly of the entire vane support.
- the invention is based on the general idea to arrange the locking portions and the complementary support portions with axial offset.
- the assembly and disassembly of the vanes is simplified because the axial movement of the vanes, which must be performed in order to establish the positive locking, is significantly reduced. Problems such as distortion, jamming and jamming along the axial contact are reduced. Since the cooperating support sections and latch sections extend in the circumferential direction, the guide blade arrangement according to the invention allows the guide vanes to be adjusted in the circumferential direction.

- the vane carrier has a plurality of connection openings, each fluidically connecting the common collection channel with one of the cavities. Due to this feature, the vane support comprises an important part of a cooling gas supply path. Said common common rail significantly simplifies the cooling gas supply through the casing of the turbomachine, since the cooling gas supply passage of the casing can be disposed in a suitable portion of the casing and because the arrangement of the cooling gas supply passage is independent of the arrangement of the vanes.
- the vane arrangement allows circumferentially adjacent vanes to be provided with a gap seal arrangement.
- Said gap seal arrangement is designed to seal a gap extending axially between each two circumferentially adjacent vanes.
