Definitions

  • the invention relates to a heat shield element assembly comprising a heat shield element, a method of mounting a heat shield element in a heat shield element assembly, another method of mounting a heat shield element in a heat shield element assembly, and a use of the heat shield element assembly having the features set forth in the preambles of each independent claim.
  • the heat shields of turbine engines such as gas turbines and turbine engines, such as those used in power-generating power plants and in larger aircraft, have correspondingly large shielded by heat shields surfaces in the interior of the combustion chambers.
  • the shield must be composed of a plurality of individual ceramic heat shield elements spaced apart from one another with sufficient clearance. This gap provides the heat shield elements with sufficient space for thermal expansion.
  • a cooling fluid in the form of cooling air is blown through cooling passages as an effective countermeasure through the gaps in the direction of the combustion chamber. 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.
  • brackets In order to perform the brackets as simple and as one piece, a construction is known in which these brackets on the one hand in the circular support in the support structure and parallel trained mounting grooves are inserted insertively, and on the other hand clamped with trained gripping portions in the formed in lateral edges of the ceramic heat shield elements Halteruten.
  • 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 no longer be mounted in this way because the mutually present adjacent heat shield elements block a tangentially directed assembly movement.
  • a last heat shield element is referred to as a dummy plate or dummy. Consequently, solutions are used with screws for attaching the last heat shield element, which allow mounting of the heat shield element in the direction of the surface normal of the support structure.
  • a known screw used for this purpose four screws which engage in the recess formed in lateral edges of the heat shield element for this purpose.
  • This solution is disadvantaged in that the assembly requires a handling problem.
  • the handling of the four screws enforces, for example, the use of fixatives such as adhesive or tape, which are not reliable, so that the screws can be lost and must be found before commissioning due to high risk of damage to a turbine.
  • the overhead mounting is difficult because the screws can tilt through the fixation by tape and thus can not be inserted into the holes provided. Since this is the last heat shield, the screws can not be positioned by hand, but must be threaded into the holes using an Allen key - without sight.
  • EP 1 701 095 A1 and EP 0 558 540 B1 describe by way of example a heat shield as stated above with the described advantages and problems.
  • the heat shield elements are referred to in the art as stones and retaining elements holding them stone holder and recessed in the side edges of the heat shield elements grooves as pockets.

  • the heat shield element has recessed depressions in the form of retaining grooves on each of two opposite side edges extending transversely to the parallel mounting grooves.
  • a heat shield element according to the invention has at least one continuous screw head opening, which pierces the cold side and the hot side of the heat shield element essentially vertically and through which the head of the respective screw is accessible and / or freely retractable up to the support structure.
  • an Allen recess of hexagonal or other shape may be formed in the head of the screw, so that the Screw can be rotated from the hot side of the heat shield element using a corresponding Allen tool.
  • the continuous screw head opening is arranged above the mounting groove.
  • a screw hole for receiving the threaded shank of the screw is present in the mounting groove of the support structure in alignment with the screw head opening .
  • Under the head of the screw serving as a stone holder spring element can be arranged and / or arranged, which extends along the cold side of the heat shield element and the mounting groove of the support structure.
  • at least one outer end of the spring element serving as a stone holder is designed as a clasping holding hook, which is equipped for engagement in the lateral recessed retaining groove of the heat shield element.
  • the spring element extends only to one of the two sides having the retaining grooves, wherein in each case two spring elements facing away from each other form a spring element pair.
  • the spring element extends to both the retaining grooves having sides of the heat shield element and thus forms an integral spring element pair.
  • the spring element is fastened by preferably at least one common screw to the support structure.

As a result, a distance is formed between the retaining hooks, which allows a threading of the heat shield element between the retaining hooks.
  • a recess is provided on the hot side of the heat shield element, which is provided for receiving the convex curvature of the spring element.
  • a hold-down is arranged, which serves to straighten by pressing the curvature of the spring element and thereby to engage the retaining hooks at the opposite ends of the spring element in the retaining grooves ,
  • the provided in the respective mounting groove of the support structure screw hole may be designed to receive the threaded shank of the screw through the support structure through and be screwed with an attachable from the back of the support structure threaded device.
  • the provided in the mounting groove of the support structure screw hole for receiving the threaded shank of the screw may be preferably designed as a blind hole of a certain sufficient depth, wherein in the blind bore further preferably a threaded insert is mountable.
  • the threaded insert can be designed in particular as a spiral insert or a Helicoil.

  • lateral recesses or pockets 5 are formed with lateral recesses 6, in which the screw shaft 15 and screw head 13 are inserted laterally.
  • a pressure distributor or disc 14 is arranged, which distributes the pressure over a larger area and thus protects the ceramic body of the heat shield element 3.
  • a heat shield element 3 with only four attached screws 13/15 and pressure manifolds 14 must now be mounted perpendicular to the support structure 30 in the prior art, and the four screw shafts 15 must be threaded into the four correspondingly arranged in the support structure 30 screw holes. Because the screws freely inserted laterally into the pockets 5 can easily fall out, they are previously fixed in their positions with an adhesive or adhesive tape. When threading, however, this adhesive connection is easily lost and the screws can either fall out or be tilted and therefore no longer meet in the screw holes of the support structure 30th
  • the cooling is carried out, for example, as a ventilation via channels and ventilation lines 25.
  • the cooling channel may be the mounting groove 40 of the support structure 30 or special channels formed in the support structure.
  • the spring plate package 19 is an additional complex component and is installed in a package sleeve 20 which is closed by a fixing plate 22. This fixing disc 22 prevents the disc spring and the threaded nut 21 from falling out when the screw 15 has not yet been inserted.

  • the hold-down 38 is pressed to the groove bottom and the curvature of the spring element 37 thereby straightened, so that the retaining hooks 36 engage on both sides in the respective lateral retaining groove 34 of the heat shield element 3 and thus hold this. Due to the predetermined spring force of the spring elements 37, the heat shield element is pressed against the support structure 30 and the thermal expansion of the heat shield element 3 is thus compensated by the spring-yielding spring elements 37.
