A stator vane including a vane root, a vane tip, a leading edge extending between the root and the tip, the leading edge having a serrated profile having a succession of teeth and of troughs each having an amplitude and a thickness, wherein a series of at least three teeth and three consecutive troughs starting from the vane root and/or from the vane tip have a growing amplitude and/or thickness.

Modulation of vane end serrations

An assembly for a primary flow path of a double flow turbomachine extending along a longitudinal axis including a reduction gear, configured to drive a fan in rotation, a stator including a plurality of vanes for straightening the primary flow path, and an intermediate casing, positioned downstream of the stator, including structural arms with fairings passing through the primary flow path, wherein a fairing and one straightening vane are connected together within the primary flow path by a connecting surface, the fairing and the vane being positioned longitudinally substantially at the reduction gear.

Straightener vane and structural arm connected in a primary flow path

An assembly for a turbine engine or turbine engine test bed, including a hub defined about a longitudinal axis, a blade, including a blade root, extending in a radial direction to the longitudinal axis, the hub including a recess capable of receiving the blade root by insertion in the radial direction, wherein the recess includes a groove, the blade root including a groove, so that the two grooves are facing each other when the blade root is inserted into the recess, the assembly further includes a seal located in the two grooves.
