Abstract (en)

The ring-shaped jacket has an air guide chamber formed between curved jacket segments and guide segments. The guide segments (30) are positioned loose with radial play. They are guided between a carrier segment (20) and distance pieces (12). These are fastened to the back of the jacket segments to project in radial direction. The guide segments have U-shaped radial webs (32) held with small axial play in guide grooves (22) of the carrier segment.

Abstract (de)

Kühlbarer Mantel einer Gasturbine oder dergleichen, mit mehreren bogenförmigen Mantelsegmenten (10), die in Umfangsrichtung aneinandergrenzend zu einem im Wesentlichen geschlossenen, ein Laufrad (110), insbesondere einer Hochdruckturbine, umgebenden Mantelring angeordnet sind, wenigstens einer ringförmigen Mantelkühlkammer (15), die in radialer Richtung zwischen den Mantelsegmenten (10) und bogenförmigen, mit einer Vielzahl von Durchgangsöffnungen (34) versehenen Leitsegmenten (30) gebildet ist, wenigstens einer Luftführungskammer (25), die in radialer Richtung zwischen den Leitsegmenten (30) und wenigstens einem Trägersegment (20) gebildet ist, sowie wenigstens einem, an dem Trägersegment (20) angebrachten Luftzuführungskanal (26), der in die Luftführungskammer (25) mündet, wobei die Leitsegmente (30) lose mit radialem Spiel gelagert sind. Hierdurch wird eine spannungsfreie Aufnahme auch im Falle intensiver Vorgänge mit hohen Temperaturgradienten gewährleistet. <IMAGE>
