Definitions

  • Part of the air is also used for sealing purposes, particularly between the rotating and stationary parts of the gas turbine 10, such as between the stator 28 and the rotor 22 (see the sealing systems 23a, 23b and 23c in FIG Fig. 1 ).
  • gaps are rinsed with air which is introduced into the hot-gas channel (see hot-gas main stream 29 in FIG Fig. 1 ) and thus prevents the entry of hot gas and thus a local overheating at this point.
  • the invention is characterized in that the swirl vanes are each arranged displaceably in a transversely varying manner in the swirl duct transversely to the flow direction, that adjusting elements are provided from a memory alloy to move the swirl vanes temperature-dependent, and that the displaceable vortex vanes each on the upstream Side are provided with a baffle, which initiates the flowing medium in the spinal canal in the narrowed by the swirl vanes cross-section.
  • the adjusting device 43 has a wall-parallel wall element arranged on the side of the blade root of the swirl blade 26 44 with associated baffle 45, which in turn can be moved by adjusting 42 of a memory alloy perpendicular to the wall.
