Air Bleed System for an Axial Turbomachine

摘要

The present application relates to a bladed stator of a turbomachine compressor, configured to straighten an annular stream of the turbomachine. The stator includes at least one annular wall configured to define the annular stream, a row of blades extending radially from the annular wall and means of pressurizing in communication with the annular stream. The means of pressurizing are configured to pressurize a chamber which is separated from a lubrication housing by a labyrinth seal. The means of pressurizing comprise at least one passage extending through the thickness of the annular wall and connecting with the annular stream. The means of pressurizing further includes at least one scoop in communication with the passage and the annular stream. The scoop is open upstream so as to capture the dynamic pressure of the annular stream.

1. A bladed stator of an axial turbomachine, comprising:
at least one annular wall configured to define an annular stream; a row of blades extending radially from the annular wall; and means for pressurizing a chamber, the means comprising:
at least one passage extending through the thickness of the annular wall and connecting with the annular stream; andat least one scoop on the annular wall on the side of the annular stream and in communication with the passage, each scoop being open in the upstream direction, so as to capture the dynamic pressure of the annular stream.
