A single-piece compressor nozzle stage for a turbine engine, the stage including two coaxial rings, connected together by radial vanes, the inner ring including an annular cavity for housing a damper for damping vibration by friction, which damper is secured to an annular abradable-material support.

A turbomachine stator stage including two coaxial shrouds, respectively an inner shroud and an outer shroud with substantially radial vanes extending therebetween, the radially outer ends of the vanes being welded to the outer shroud and the radially inner ends of the vanes passing through orifices in an outer ring of the inner shroud, the inner ends being held by elastomer spacers in an annular cavity formed between the outer ring and an inner ring that is fastened to the outer ring.

Stator stage for turbomachine compressor

A low of compressed air originating from a compressor stream ( ) is drawn off through first orifices ( ) towards ducts ( ) leading outside the casing, creating a flow division through adjacent cavities ( ) in the casing ( ). These arrangements make it possible to carry a large air flow even if the cavity cross sections ( ) are small.
