Embodiment Construction

[0129] The figures of this description illustrate various embodiments of single and / or multi-ply CMC panels provided for system arrangements. Basically, CMC panels can be designed with individualized fiber structures according to operational requirements. A proportion of fibers may have different diameters, which are intended to carry mechanical loads (in the case of larger diameters) and thermal stresses mainly during flow application operations.

[0130] Figure 4 shows various examples of panel combinations. In general, a panel means an arrangement of plies or a woven fibrous structure. Figure 4a ) shows a standard CMC panel, also referred to as Panel 1, using a standard arrangement and / or woven fiber structure. The different layers in a multi-layer panel do not necessarily have the same fiber orientation or weave architecture. according to Figure 4b ) brings together a standard CMC panel (made from one of several plies of standard ceramic tissue) and a "cooling patter...

Abstract

A method of fabricating a structural cooling panel comprising: cutting desized 2D ceramics into tissue; infiltrating the tissue with slurry by at least one blade coating method; laminating the tissue into a multilayer panel wherein the slurry is impregnated after each layer , where the tissue has combined fibers and / or preformed cooling holes; drying; demoulding; sintered multi-layer panels, wherein part of the combined fibers burns out during the sintering process, leaving behind a female framework forming the cooling structure, and / or preformed Constructed cooling holes define the cooling structure; finishing using: i) post machining, and / or ii) surface smoothing / reworking, and / or iii) coating application, and / or other procedures.

Description

technical field [0001] The present invention relates to an advanced concept of modular industrial gas turbine (IGT) components based on the principle of using the most suitable materials in the industrial range for each field of IGT components according to the state of the art. It refers to the method of manufacture of insulating structures or panels, cooling structures or panels applied to components to adapt the final component to a specific function. [0002] Furthermore, the present invention relates to i) combined panel structures; ii) special handling of the various panels forming combined panel structures; iii) manufacturing concepts related to structural cooling panels; iv) various IGT components assembled from combined panel structures . [0003] Furthermore, the invention relates to the fixing of modular structural components and CMC airfoils, in particular guide vanes or rotor blade airfoils, on a metal platform with a metal core of structural IGT members as descri...
