- the respective fastening element comprises a hook protruding from the platform, bent at an angle, which is adapted in its shape and contour to the associated receiving groove of a Leit ⁇ blade carrier.
- a possible alternative to this is a substantially straight profile piece that is moved into a polygonal inclusion in the turbine housing a ⁇ .
- the connecting element is positively fixed in a matched to the shape of the connecting element depression or groove of the platform.
- a positive connection is for example given by the fact that the platform in the edge region of the recess or the groove has a number of projections which engage around the kausele ⁇ ment each on its side facing away from the support surface.
- the connecting element is then laterally lent into the recess or the receiving groove of the platform is inserted and then fixed in a suitable manner to the case ⁇ play positively, positively and / or cohesively, against lateral slipping. Because the connection forces are essentially by the projections positively embracing the connecting element are received, the additional fixation must be designed only for relatively low loads.
- a cohesive connection preferably by soldering or welding, may be provided.
- the respective fastening element for a high mechanical load capacity is preferably produced integrally from a one-component workpiece.
- the attachment hook can be milled or extruded as a straight profile piece and bent in a second operation in the required radius.
- the buildin ⁇ actuating element is made of a nozzle segment in comparison to the remaining less resistant to high temperatures, but made tougher material.
- the guide vane or Leitschau ⁇ felsegment for secure attachment to the guide vane on a plurality of fasteners preferably each of the fasteners is in the manner described above separately manufactured and ausgestaltetes component.
- a gas turbine typically includes a plurality of turbine stages, each of the turbine stages including a plurality of stator vanes circumferentially around the flow passage on the turbine housing, which in their entirety form a row of vanes.
- a ⁇ in each case a plurality of adjacent guide vanes to a guide blade segment or a "Mehrung" summarized in.
- Each of the guide vanes the or each vane ⁇ segment expediently has a platform with hakenarti ⁇ gen fastening elements, wherein the specifications for the hooking profile with regard to bending angle and / or bending dius usually vary with the installation position, ie in particular depend on the turbine stage or the guide vane row.
- the material selection for the fastener can be optimized to the Verhakungsan petitionen out, especially in terms of load bearing, wear and / or seal.
- Leitschaufelsegmentes is much easier. Tolerances can be set or adhered to more easily.
- An interlocking profile can be used as a standard for all turbine stages / performance classes and adapted to the respective intended use by different bending radii. Casting problem areas are avoided in the casting. The wax tools for the vanes are simpler, have fewer inserts or slides.
- FIG. 2 shows a guide blade with a fastening element ge ⁇ according to a second embodiment
- the illustrated in Figure 1 in a schematic side view cut-way and partially cut Leit ⁇ scoop 2 comprises a extending in the direction of the blade axis 4 profiled airfoil 6, to which in the region of the blade root a substantially transverse to the blade axis 4 oriented platform 8 is formed , In the installed state of the vane 2 which is oriented toward the blade 6 toward "top 10".
- an outer Be ⁇ delimitation of a hot gas leading flow channel in a gas turbine (not shown) 12 or back of the platform 8 is a number of ha ⁇ kenartigen fasteners 14, by means of which the guide vane 2 in an associated vane support (not shown) mounted on the turbine housing / is attached.
- the image section shown here is only one of the fastening elements 14 ⁇ visible, which is mounted with respect to the axial direction 16 near the trailing edge of the blade 6; another fastener is disposed in the vicinity of the leading edge not shown here.
- the fastening element 14 is specifically adapted to the mechanical loads associated with the entanglement in the guide vane carrier in the case of a production that is simple and inexpensive.
- the fastener 14 is designed as a separate, independent of the remaining vane 2 and only subsequently connected to her component, wherein the material used for the fastener 14 ⁇ material is less resistant to high temperatures, but it is tougher than the material from which the blade 6 and Platt ⁇ form are made. 8
- the fastening element 14 comprises in addition to a projecting from the rear ⁇ side 12 of the platform 8, approximately at right angles angled mounting hook 18 thereon a molded connection plate 20 with a rectangular base.
