Abstract: A turbomachine includes an enclosure lubrication and pressurization assembly having at least one lubricated enclosure protected by two seals. The turbomachine further includes a primary flow path surrounding the at least one lubricated enclosure, and in which circulates a primary flow passing through at least one compressor of the turbomachine. The assembly further includes an electric compressor supplied with air and connected to the at least one lubricated enclosure in order to introduce air under pressure into the enclosure through the seals.

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.
Abstract: The invention relates to an electronic circuit (1) comprising a plurality of printed circuits (2) connected by at least one bus bar (4), each printed circuit (2) comprising at least two superposed layers enclosing at least a portion of said at least one bus bar (4), so as to cover said at least one bus bar (4).
