ABSTRACT:
The pattern relates to a cover for a turbomachine nozzle, the cover having a plurality of patterns each with an outline of triangular shape having a base and two vertices that are spaced downstream and interconnected by a side. For each pattern, the vertices present respective curved outlines and they are interconnected by a curved portion presenting a radius of curvature greater than the radii of curvature of the outlines of said vertices, each side being connected to the trailing edge of the cover via a curved outline presenting a radius of curvature greater than the radii of curvature of the outlines of the vertices and greater than the radius of curvature of the outline of the curved portion, and the vertices and the curved portion are inclined radially towards the inside of the cover, with the curved portion being radially offset outwards relative to the vertices.
