BLADE AND GAS TURBINE

摘要

The blade (3) is of modular construction, and has a fastening element. It is constructed from several segments (3a-d) of different dimensions, which are connected positively and/or non-positively. The joint surfaces are horizontal, vertical, and/or diagonal. The segments are of different materials, e.g. high heat-conductive material, high temperature-resistant material, ceramic, metal, and/or metal alloy, and plastic. All segments are coated. And they may have a hollow chamber (6) filled with a material different from the segment material, e.g. foam (7). Blade nose (4) and rear edge (5) are also formed by segments.
