Abstract

Ein System enthält ein Turbinengehäuse (98) mit einem ersten Haken (100), der für eine Vereinigung mit einem zweiten Haken (104) konfiguriert ist, um ein Turbinendeckband (38) um mehrere Turbinenschaufeln (36) herum zu unterstützen. Das Turbinengehäuse (98) enthält einen Kühlmittelkreislauf, der dafür konfiguriert ist, den Abstand zwischen dem Turbinendeckband (38) und den Turbinenschaufeln (36) auf der Basis eines Kühlmittelstroms durch den Kühlkreislauf einzustellen. Der Kühlmittelkreislauf enthält mehrere sich in den ersten Haken (100) erstreckende erste radiale Kühlmittelkanäle (166, 168).
