Abstract (en)
[origin: EP1249577A1] The turbine has axially displaceable casing parts (14, 15) to compensate for thermal expansion, which form the outside of a funnel-shaped gas channel (7). At least one of these casing parts is driven by a motor for its axial displacement, thus altering the width of the blade tip gap as a result of the funnel-shaped design of the casing parts.
