Angular sector of a stator for a turbine engine compressor, a turbine engine stator, and a turbine engine including such a sector

摘要

A stator angular sector for a turbine engine compressor and including: an outer shroud and an inner shroud; and at least one vane extending radially between the shrouds and connected thereto at its radial ends. At one of its axial ends the outer shroud includes a cavity opening out to the axial end and extending between a radially-inner tongue of the outer shroud to which the radially-outer end of the vane is connected and a radially-outer tongue of the outer shroud carrying a mounting mechanism for mounting the stator angular sector to a casing of the engine. An abutment-forming insert is housed at least in part in the cavity, the abutment-forming insert configured to limit radial movements of the radially-inner tongue by contact and thus to modify vibratory behavior of the radially-inner tongue.

1. A stator angular sector for a turbine engine compressor, the sector extending around an axis of radial symmetry and comprising:
an outer shroud and an inner shroud arranged coaxially one inside the other; and at least one vane extending radially between the shrouds and connected thereto at its radial ends; wherein the outer shroud includes mounting means at each of its axial ends for mounting the stator angular sector to a casing of the engine; wherein the outer shroud includes, at least one axial end, a cavity opening out to the axial end, the cavity extending between a radially-inner tongue of the outer shroud to which the radially-outer end of the vane is connected and a radially-outer tongue of the outer shroud carrying the mounting means for mounting the stator angular sector to the casing of the engine; and wherein at least one abutment-forming insert is housed at least in part in the cavity, the abutment-forming insert configured to limit radial movements of the radially-inner tongue by contact and thus to modify vibratory behavior of the radially-inner tongue.
