Abstract: An electronic board comprises a plane printed circuit, a thermal drain and an expandable locking means positioned along one edge of the printed circuit comprising a part for transmission of movement and a part mobile in translation along an axis including a component perpendicular to the printed circuit. The part mobile in translation has at least one recess opening onto a face of the expandable locking means perpendicular to the printed circuit. The locking means is designed to rigidly fix the board in a chassis and to press the thermal drain against a face of the chassis. The printed circuit comprises a region which enters into the recess or recesses of the expandable locking means.

Abstract: A movable blade for a turbomachine, the blade including at its distal end a top portion including opposite first and second side edges and upstream and downstream sealing wipers. Each of the first and second side edges has a substantially Z-shaped profile between the upstream and downstream wipers. On a side of the first side edge, the platform includes a first outwardly projecting rim not connected to either of the upstream and downstream wipers. The platform includes a second outwardly projecting rim, the second rim including a downstream portion connected to the downstream wiper and extending along the second edge, and an upstream portion extending the downstream portion as far as the upstream wiper, and set back relative to the second side edge.

Abstract: A coiled electronic power component configured to be mounted on a base, the component including an axially extending magnetic core around which a plurality of turns are wound to form a magnetic coil, and at least one bracket for mounting on the base. The mounting bracket includes at least one drain surface in thermal contact with the magnetic core and/or the plurality of turns to drain calories from the magnetic core and/or from the plurality of turns to the base during operation of the component. The mounting bracket has an equivalent thermal conductivity of greater than 400 W·m?1·K?1.

Abstract: A method of manufacture of a wax model of an annular bladed turbomachine stator assembly includes in succession the positioning, in a mold, of a core intended to form the impression of a cavity of a blade of the assembly, the injection of a wax in the mold, and the removal of the wax model fitted with the core from the mold. The core is manufactured in metal and is positioned such that its radially internal end is housed in the portion of the mold defining the blade including the cavity, away from the radially internal end of this portion of the mold.
