Abstract: A matrix for exchanging heat between a first fluid and a second fluid, in particular for an air-oil application in a turbine engine, includes an envelope defining a flow path of the first fluid and a network extending into the flow path and in which the second fluid flows. Along the axis defined by the curvature of the matrix, the dimensions of the envelope vary circumferentially (T(A)) and radially (R(A)). The matrix may be used with a heat exchanger.

Abstract: An aircraft bypass turbojet engine lubrication unit includes from three to five superposed pumps, a body housing the pumps and an internal passage in the body for communicating with each of the pumps. The material of the body exhibits a stack of layers in a direction of stacking, the pumps being housed in the said stack of layers. The passage exhibits an end in the direction of stacking of the layers and an internal profile, for example triangular, with two straight lines which form the said end and which are inclined with respect to the stacked layers. The lubrication unit may be manufactured by additive manufacturing in layers.

Abstract: The invention relates to a cross-country or ski touring binding for connecting a boot to a ski in an articulated manner, comprising a binding base body with a standing surface for a sole of the boot and a ski contact surface for at least indirect contact with the ski. The binding has a holding device comprising a receiving element which allows the boot to and a holding element for holding the boot on the receiving element. The holding element moves between a closed position holding the boot on the receiving element and an open position releasing the boot. The binding also has an actuating element with a rotating handle for switching the holding element from the closed to the open position, comprising a substantially disk-shaped, eccentrically mounted force-transmission element received in a recess of the holding element.

Abstract: A strainer for filtration in an oil circuit of a turbine engine, in particular a multi-flow turbojet engine, is housed in a bore of a lubrication assembly. The oil serves to lubricate and cool mechanisms of the turbine engine. The strainer includes a filtering portion as an angular tube portion and a holding structure for the filtering portion. The structure forms a thickening and exhibits rings and structural posts. A magnet is added in a socket formed by the structure. The structure and the filtering portion are integral and are produced by additive manufacturing, which simplifies production. The application likewise relates to a method of producing the strainer.
