摘要： The invention relates to a preform for a turbine engine vane, obtained by means of three-dimensional weaving, comprising: a first longitudinal segment (31) intended to form at least one portion of a vane root; a second longitudinal segment (32) extending upward from the first longitudinal segment, intended to form at least one portion of a pole; a third longitudinal segment (33) extending upward from the second longitudinal segment, intended to form a blade part; a first transverse segment (34) extending transversely from the junction between the second and third longitudinal segments, intended to form a first platform; and a first inclined segment (36) extending from the junction between the first and second longitudinal segments to the first transverse segment, intended to form a retaining leg (26) for the first platform.

摘要： Disclosed is a preform for a blade of a turbomachine, comprising a main fibrous preform which is obtained by a three-dimensional weaving process and which includes a first longitudinal section forming a blade root (21), a second longitudinal section that extends the first longitudinal section in the vertical direction and forms part of an airfoil (22), a first transverse section that extends transversely from the connection between the first and second longitudinal sections and forms a first land (23) in which the preform includes at least one stiffener (40) that is mounted on the main fibrous preform along at least a portion of the distal edge of the first transverse section.

摘要： Disclosed are a fibrous preform for a blade of a turbomachine, a one-piece blade made from a preform of said type, a bladed wheel, and a turbomachine comprising a blade of said type; the fibrous preform is obtained by a three-dimensional weaving process and includes a first longitudinal section (41) forming a blade root, a second longitudinal section (42) that extends the first longitudinal section in the vertical direction and forms part of an airfoil, and a first transverse section (51) that extends transversely from the connection between the first and second longitudinal sections and forms a first land; the transverse section includes a disconnected portion that has an upper face (51b) and a lower face (51a), and an insert (61) is placed between the upper and lower faces of the disconnected portion of the first transverse section.
