Abstract

PURPOSE: To prevent hot gases from stealing into the space between staionary vanes and movable vanes by alternately arranging a plurality of fins and resistors of column- and plate-shaped projections between the vanes of both types of a gas turbine.
CONSTITUTION: A plurality of axial plates 5 and 5 are mounted on a rotor disc 4 which is connected to the movable vanes 1 of a gas turbine. The plates 5 carry at their leading ends movable vane side radial fines 5'. A partition 3 is connected to the stationary vanes 2 facing the movable vanes 1, and a plurality of fins 6 are arranged on the partition 3 such that they are positioned in an alternate relationship with the fins 5 of the plate 4. The partition 3 is formed with a plurality of resistors 10 and 10' of column- and plate-shaped projections. The hot gases stealing into the space between the vanes 1 and 2 are used to generate a voxtex flow 11 between the fins 5 and 6 so that they can be prevented from stealing further inside
