Abstract

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.
