Abstract: A ventilation ring for a bearing support member of an aircraft turbine engine includes two or more tubular walls and one or more spacer walls. The two or more tubular walls extend opposite each other, and one or more of the tubular walls includes a main portion and a base, the base having a thickness greater than a thickness of the main portion. The one or more spacer walls connect the two or more tubular walls. The one or more spacer walls have one or more apertures extending into the base and a rim around the aperture. An entirety of the rim has a thickness greater than a thickness of the spacer wall at a distance from the rim.

Abstract: Method for manufacturing an aeronautical part by additive manufacturing, the part to be manufactured extending around a central axis and comprising at least two walls angled with respect to one another and connected to one another by means of at least one connection section comprised in a connection plane perpendicular to the central axis, the method comprising: providing a digital model of the part to be manufactured, orienting the digital model with respect to a vertical construction direction of the part so that the central axis of the part has an angle ? of between 0.1° and 1°; and manufacturing the part by additive manufacturing from the digital model obtained in the orientation step.

Abstract: Turbomachine output bearing support extending according to an axial direction, said support being formed by one and the same piece and comprising an annular inner wall having an inner side and an outer side, an annular outer wall and a twist support.

Abstract: A method for obtaining, by additive manufacture, a component including at least one recess, this method including: a step of forming, by additive manufacture, a one-piece blank component, in which the at least one recess contains a support including a core in the form of a block of material and cellular elements that connect the core to the recess; and a step of detaching the support from the rest of the blank component in order to expose the recess.

Abstract: A bearing support for an aircraft engine, manufactured, in one piece, by powder-bed additive manufacturing from a manufacturing platform, including a cylindrical element including an annular stiffener with a cross-section that changes along its circumference, this stiffener being formed with alternating portions having a ?-shaped cross-section, needing to be supported during the manufacture, and portions having a Y-shaped cross-section that are not supported during the manufacture.
