Abstract
The invention relates to a method for producing a shielding cartridge (1) of a turbomachine element (10), said method comprising a step of winding a carbon wire (3) comprising a plurality of fibres about a longitudinal axis and a step of trapping and preserving the outside surroundings of the wound-up wire (3) in a housing (2).
Claims11
A method for producing a shielding cartridge of a turbomachine element, the method including:
- winding a carbon wire about a longitudinal axis, the wound carbon wire including a plurality of fibers, and
- trapping and preserving the wound carbon wire in a housing, wherein the housing is closed by a cover, the housing and the cover comprising a metallic material or a metallic alloy,
- wherein the wound carbon wire is arranged in a plurality of rows in the housing, each row extending along a direction perpendicular to the longitudinal axis.
A shielding cartridge of a turbomachine element, including
- a housing,
- a carbon wire wound about a longitudinal axis, wherein the wound carbon wire is trapped and preserved from outside surroundings in said housing, wherein the wound carbon wire includes a plurality of fibers, and
- a cover fixed to the housing, wherein the housing and the cover comprise a metallic material or a metallic alloy,
- wherein the wound carbon wire is arranged in a plurality of rows in the housing, each row extending along a direction perpendicular to the longitudinal axis, and wherein the wound carbon wire is not fixed to the housing.
