Abstract
The invention relates to a secondary flow stator vane (1) for a turbomachine, comprising skins (2, 3) having end portions (21, 31) delimiting an opening (5) and a cavity (4) therebetween, which skins diverge from one another in a direction (Y). A filler material (41) is located in the cavity (4) at a distance from the opening (5). A reinforcement (6), the density of which is higher than the density of the material (41), comprises a first reinforcement portion (61) located in the cavity (4) against the material (41) and a second reinforcement portion (62) for closing the opening (5) between the portions (21, 31) to form a single piece.
Claims15
A secondary flow guide vane of a turbomachine, comprising a first outer skin and a second outer skin, which are made of a first composite material and which are connected to one another,
- the first outer skin comprising a first end part, the second outer skin comprising a second end part distant from the first end part,
- the first end part and the second end part being located on the same mounting side of the vane, delimiting between them an opening and branching away from one another along a thickness direction,
- wherein
- the vane further comprises:
- a cavity, which is located along the thickness direction between the first outer skin and the second outer skin and which opens into the opening,
- a filling material which has a first density and which is located in the cavity and at a non-zero distance from the opening,
- a reinforcement, which has a second density greater than the first density and which comprises a first reinforcing part located in the cavity and against the filling material and a second reinforcing part, which closes the opening between the first end part and the second end part,
- the first reinforcing part forming a single piece with the second reinforcing part.
