Vane with sealed lattice in a shroud of an axial turbomachine compressor

An axial flow turbine engine compressor, comprising:

• an annular vein guiding an axial annular flow;
• and
• a stator comprising:
• an annular wail comprising:
• an annular guiding surface guiding said axial annular flow;
• and
• a circular row of stator vanes, at least one of the stator vanes comprising:
• an airfoil extending radially through the axial annular flow from the guiding surface;
• and
• a securing portion, the airfoil and the securing portion being radially stacked;
• wherein the securing portion of the vane comprises:
• a lattice which is secured to the wall in order to fix the vane to the wall via the lattice, the guiding surface being radially placed between the lattice and the airfoil of said vane,
• wherein the lattice is a three-dimensional lattice with interconnected rods which are joined to each other so as to form meshes, the lattice comprising a plurality of meshes over the thickness and over the length of the airfoil and in the radial direction,
• wherein the stator comprises:
• a layer of abradable material for cooperating by abrasion with the rotor of the compressor, the lattice being at least partially arranged in the radial thickness of the layer of abradable material, and said layer filling the lattice.

An axial flow turbomachine, comprising:

• an annular primary vein guiding a primary flow;
• an annular secondary vein guiding a secondary flow, the secondary vein being around the primary vein;
• an inner shroud embraced by the primary flow;
• and
• several annular rows of stator vanes, at least one of the stator vanes comprising:
• an airfoil extending radially from the inner shroud through the primary flow;
• and
• a securing portion placed inside the inner shroud, the securing portion of the vane comprising:
• a lattice which is secured inside the inner shroud in order to fix the vane to the wall via the lattice,
• wherein the lattice is a three-dimensional lattice with interconnected rods which are joined to each other so as to form meshes, the lattice comprising a plurality of meshes over the thickness and over the length of the airfoil and in the radial direction,
• wherein the airfoil comprises:
• a solid body which extends over the majority of the radial height thereof,
• the lattice being broader in the circumferential direction than said airfoil.
