摘要:
A sector of a compressor guide vanes assembly or a sector of a turbomachine nozzle assembly. It comprises an inner ring sector (4), an outer ring sector (6) and a multitude of blades (8) connecting the inner ring sector (4) to the outer ring sector (6). The outer ring sector (6) or the inner ring sector (4) comprises radial cuts (10) situated between two consecutive blades (8) in such a way as to split them into the same number of elementary sectors as there are blades. Housings (14) are provided, secant to the radial cuts (10), damping inserts (16) being positioned in said housings.

摘要:
An assembly of sectorized fixed compressors for a turbomachine compressor is disclosed. The assembly is a single piece and includes two coaxial rings connected by radial airfoils. The outer ring includes two annular mounting lugs on a casing of the compressor. At least one of these annular lugs is connected to the outer ring in a zone axially separate from the zone for connecting the leading edges or trailing edges of the airfoils to the outer ring.
摘要:
An assembly of sectorized fixed compressors (50) for a turbomachine compressor, this assembly being made in a single piece and comprising two coaxial rings (20, 52) connected by radial airfoils (24), the outer ring comprising two annular mounting lugs (56, 66) on a casing of the compressor, at least one of these annular lugs being connected to the outer ring in a zone axially separate from the zone for connecting the leading edges (26) or trailing edges (28) of the airfoils to the outer ring.
