  • Patent number: 11879344
    Abstract: A device for making a fan or compressor for the aeronautical industry includes an annular casing with a main axis (A) and defines an internal flow duct for a gas flow along this axis. The device further includes a bladed wheel mounted inside the casing and having an axis of rotation coincident with the axis (A) of the casing. A system for retaining debris in the event of breakage of the bladed wheel has a retaining annulus mounted around the casing, which includes two radially outwardly projecting annular bosses located respectively upstream and downstream of the bladed wheel. Upstream and downstream edges of the retaining annulus are applied and attached to the bosses.
