Definitions
- the invention relates to a heat shield element according to the
- This cooling air is also used to specifically blow on the metallic brackets and thus to cool, with which the ceramic heat shield elements (CHS, Ceramic Heat Shields) are clamped to the support structure.
- CHS Ceramic Heat Shields
- the heat shield elements are successively inserted with the holders in the grooves of the support structure, wherein the trailing elements obstruct the previously positioned in their positions.
- a circular series of heat shield elements can be formed in a combustion chamber of a gas turbine.
- the last remaining heat shield element can not be mounted in this way because the mutually present, adjacent heat shield elements block a tangentially directed assembly movement. Often one becomes
- Screw through the fixation can tap with tape and thus can not be inserted into the holes provided. Since it is the last heat shield element, the screws can not be positioned by hand, but must by Allen - without sight - in the
- the present invention makes it a task, a
- Heat shield element having at least one side wall, wherein the side wall at least one recess with a in
- Direction of a support structure facing passage includes.
- a fastening screw can be introduced, which passes through the passage for the vertical fastening of the
- Heat shield element on a provided in the support structure screwing is feasible.
- the passage in the side wall is a securing means which is at least partially formed by the side wall. The securing means causes the lateral falling out of the fastening screw from the heat shield element in the
- Heat shield element is significantly shortened.
- the securing means prevents a lateral falling out of the fastening screw from the passage during assembly.
- the securing means is a wedge-shaped
- the securing means is a web-shaped
- the web-shaped side wall piece has a
- Fixing screw can be so easy to her

- Fig. 2 shows a plan view of a first
- FIG. 3 shows a partial cross-sectional view through a first heat shield element according to the invention
- Fig. 4 shows a plan view of a second
- Heat shield element according to the invention.
- each recess 4 further has in the direction of the support structure 17 facing passages, which are formed in the prior art as a lateral recess 1.
- a fastening screw 18 is inserted laterally.
- Screw head of the fastening screw 18 is a disc or an angle plate 2 is attached, which the
- Angle plate 2 can thus be inserted laterally into the lateral recess 1 and recess 4. In the head of the
- Fixing screw 18 is a mold cavity for receiving a correspondingly shaped tool tip of a
- Inbussteckeducationen performed, but may also have other forms, such as cross or transverse slot.
- Fixing screw 18 is in each case an access opening 5 on the part of the hot side 21 of the heat shield element 13
- this access opening 5 is substantially smaller than the diameter of the head 2 of the fastening screw 18 and is dimensioned such that it is sufficient to allow a screwing tool to pass.
- Recesses 4 to the metallic discs 2 and heads of the mounting screws 18. Further, the recesses 4 are purged by the cooling fluid, which is injected through the intermediate gaps d from the support structure 17 into the combustion chamber to lock the wells 4 against the entry of hot gas ,
- the intermediate gap d is provided to the thermal
- Each fastening screw 18 is screwed into a screw in the support structure 17, in the present Example is executed in each case as a disc spring assembly 19.
- a threaded nut (not shown) serves to secure the
- Disc spring assemblies 19 provide for a resilient yielding attachment of the heat shield element 13, which is required to z. B. due to thermal and thermoacoustic
- FIG. 2 shows a plan view of a first heat shield element 14 according to the invention.
- the heat shield element 14 has a depression 4 with a passage 30 in the direction of
- Support structure 17 ( Figure 1) for vertically attaching the heat shield member 14 to the support structure 17 ( Figure 1) by means of the attachment screw 18 (Figure 3) to a bolting means 19 ( Figure 1) provided in the support structure 17 ( Figure 1). 1) .
- an oblique recess 31 is now mounted in the side wall 16, in which the
- Fixing screw 18 (Fig. 3) can be inserted from the outside.
- Fig. 3 shows the introduction of a fastening screw 18 in such a heat shield element 14.
- the fastening screw 18 is inserted from the outside. Subsequently, the fastening screw 18 is tilted 40 and is thus brought into its final mounting position. By tilting 40 of the head of the fastening screw 18 slides into the recess 4 and the stem of the fastening screw 18 into the passage 30.
- a wedge-shaped side wall portion 44 is formed at the passage 30, which serves as a securing means. This wedge-shaped
- Heat shield element edges are prevented.
- the recess 31 can also be introduced in the manufacture of the heat shield element 14 with equal, so that here no

- Securing means a web-shaped side wall piece 41. This is attached to the passage 30.
- Fixing screw 18 (Fig. 1) counteracts in the direction of the opening 42.
- the heat shield element 14 now has more ceramic material on the side wall 16 in the region of the depression 4 than the heat shield element 13 with the
