Abstract: The method for manufacturing a blade (32) of a turbomachine (100) comprises: —manufacturing a part (4) comprising an air flow path zone (10) and a layer (20) covering the zone, the layer having cavities (21) forming a periodic pattern, the manufacture taking place by injecting a mixture comprising a binder and a power; —removing a larger part of the binder from the part; —sintering the part, and —removing the layer (20) from the part to obtain the blade (32).

Abstract: A sector of a turbine stator for a turbine of an aircraft turbomachine, the sector having an outer platform and an inner platform which are coaxial along an axis. The sector further includes at least one blade which connects the outer and inner platforms together, with the blade being variable-pitch about an axis of rotation of the blade. The blade can include an aerodynamic body delimited radially by a head and a root, the head being placed with a first functional clearance in an opening of the outer platform, the root being placed with a second functional clearance in a cavity of the inner platform, the axis of rotation of the blade being located downstream of the head and the root.

Abstract: A turbine engine has a blade with lower and upper surfaces. The blade has a root at a radially external end and includes a transverse head section in a plane perpendicular to a radial direction of the blade, taken at the radially external end with a first center of gravity. The root has a second center of gravity defined in a plane parallel to the transverse head section and transversely offset from the first center of gravity. The second center of gravity is defined in a predetermined zone at least partly demarcated by a V that is open towards the lower surface and includes a peak, the orthogonal projection of which on the transverse head section is located on the first center of gravity.

Abstract: To increase the inertia of a sealing lip of a blade for an aircraft turbine engine, and thus improve the service life of such a sealing lip, the sealing lip is conformed so as to have a trough in the outer surface thereof and a corresponding boss in the inner surface thereof, the trough and the boss being defined based on a connection cross section of the sealing lip to a blade body, and being formed at a distance from a free axial end of the sealing lip.
