Heat shield element arrangement comprising screw threading means and method for installing a heat shield element

Abstract

The arrangement has multiple of heat shield elements (3) arranged adjacent to each other at a supporting structure (30). The heat shield elements are fixed at the supporting structure using a screwing shaft (15) in a laminated spring packet (19) that is provided in the supporting structure. The packet provided in the supporting structure is equipped with a funnel shaped screw threading unit (33), into which the fixing screw is guided and inserted. The funnel shaped screw threading unit is fixed at the laminated spring packet in a force fit manner. An independent claim is also included for a method for mounting the heat shield element arrangement.

Description

technical field

[0001] The invention relates to a heat shield element arrangement with a heat shield element, a screw lead-through, a method for mounting said heat shield element in a heat shield element arrangement and a method with the features described in the individual independent claims Application of the heat shield element arrangement of the features described in the preamble of . Background technique

[0002] To be able to withstand temperatures between 1000°C and 1600°C, effective ceramic heat shields are used in many technical applications. In particular, turbine heat shields such as gas turbines and turbine engines, which are used in power plants and large aircraft, have relatively large surfaces in the interior of their combustion chambers that are protected by the heat shield. Due to the thermal expansion and the large design dimensions, the heat shield has to be composed of a large number of individual heat shield elements made of ceramic, which are spaced fr...
