Abstract: The invention provides a rotary-wing aircraft rotor fitted with a connector device for connecting electrical power between a hub (1) and blades (2) of said rotor. For each of the blades (2), a wired connection (4) provides an electrical connection between the hub (1) and the blade (2). A guide path (13, 14, 15, 16, 17) holds the wired connection (4) in shape and guides it under tension to move over itself, accompanying the pivoting movement of the blade root (3).

Abstract: A rotorcraft rotor fitted with a device for damping lead-lag oscillations of the blades (2) of the rotor. The blades (2) are hinge-mounted on a rotary hub (1) of the rotor via respective sleeves (3). The damper device comprises a set of dampers (6), each individually housed in a respective one of said sleeves (3) and deformable between two fastening points (8, 9), one with the sleeve and the other with an engagement member (7) for engaging the hub (1) via a linkage (10). For each of the sleeve (3), the damper (6) housed by a given sleeve (3) is in hinged engagement with the linkage (10) via a lever arm (11) hinged to the sleeve (3).

Abstract: An electrical power supply device (10) provided with electrically-conductive metal electrical connection means (12) secured to an electrical power supply wire (11), said connection means (12) comprising a first portion (13) connected to said power supply wire (11), followed by a second portion (14) that extends longitudinally and that is suitable for being permanently bonded to a resistor element (3) that is provided with a plurality of electrically-conductive layers (4). Said second portion (14) is tapering, presenting thickness (e) that decreases, starting from said first portion (13), said second portion (14) having at least one slot (15) passing through said second portion (14) in said direction in elevation.

Abstract: Method for fabricating a reinforcing coating for a part made of composite material. Pre-impregnated reinforcing fibers are used in the form of slivers and said slivers are laid on the part in two layers of longitudinal slivers by being placed thereon. This fabrication makes provision for using an angular orientation for the slivers of each layer respectively of 0° and of some other angle relative to said determined direction of the solid body for covering using an interlaced pattern type that gives layer crossing lines parallel to a longitudinal axis of the solid body for covering, which pattern type is selected to form interlacing patterns that limit the number of layer crossing lines along the longitudinal axis of the solid body for covering to a single line.

Abstract: A heater mat for using the Joule effect to heat an aerodynamic surface. The heater mat is provided with a resistor element including at least two substantially parallel segments of electrically-conductive fibers disposed on the aerodynamic surface. The segments come from a single strip of electrically-conductive fibers, with two adjacent segments being obtained by folding a portion of the single strip at least twice.

Abstract: A connection endpiece placed on a resistor element provided with at least one layer of electrically-conductive fibers, the endpiece serving to connect a power supply wire electrically to the resistor element. The endpiece includes at least one metal plate having a top face for connection to the power supply wire, and provided with at least one rigid metal connector member of substantially flat shape arranged at a first end of the metal plate and connected to at least one layer of electrically-conductive fibers of the resistor element, the top face of the metal plate being covered in a removable anti-adhesive covering.

Abstract: In order to remove a plate made from a material that can be heated by electromagnetic induction and retained on a supporting member by a heat-fusible adhesive, an inductor is displaced facing at least one strip of the plate in order to heat the strip by induction and heat the adhesive by conduction until the adhesive softens, and a tearing tool is driven so as to tear out the heated strip by hot-peeling. The inductor and the tearing tool are displaced jointly relative to the plate and the supporting member by means of a mobile frame, which is displaced on a stationary frame on which the supporting member and the plate are fixed.
