TURBINE HAUTE-PRESSION DE TURBOMACHINE

摘要

The turbine (110) has a distributor (12) provided with fixed blades. An impeller is rotatably mounted in downstream of the distributor. An annular downstream radial wall (42) is integrated to an external case (40) of the turbine. The annular external structure has an annular upstream radial wall (50) arranged opposite to and remote from the downstream radial wall. The downstream radial wall carries an axial support unit (162) supported on the upstream radial wall for axially retaining the external structure of the distributor with respect to the case.
