Definitions

  • This recess in the gas turbine may be arranged between two adjacent vanes or two adjacent blades of the gas turbine.
  • FIG 7 the positive locking of an axial seal 31 with the circumferential seal 29 by means of such a hook 37 is illustrated in detail.
  • the axial seal 31 comprises two layers 39 and 41 of the metal strip, too.
  • the axial seal 31 may be inclined a bit and this inclination of the axial seal 31 does not affect the circumferential seal 29.
  • the lug 43 is made of a separate piece of bent metal and is fitted between the two ends 45 of the inner layer 35.
  • the gas turbine namely the blades 7 comprise recesses 47, which cooperate with the lug 43 in a way that the circumferential seal 29 cannot move relative to the blades 7 in circumferential direction.
