Assembly for gas turbine, associated gas turbine

An assembly for gas turbine, comprising:

• a first part and a second part installed circumferentially around a longitudinal axis of turbine, where the first part has a first side face adjacent to a second side face of the second part, where a first aperture made in the first side face faces a second aperture made in the second side face, and where the first aperture and the second aperture each have a radially internal face and a radially external face;
• a monobloc seal consisting of a sealing plate fitted inside the first aperture and the second aperture;
• wherein the sealing plate includes:
• a first longitudinal face installed opposite the radially external face of the first aperture and the radially external face of the second aperture,
• a second longitudinal face opposite the first longitudinal face, where the second longitudinal face is installed opposite the radially internal face of the first aperture and the radially internal face of the second aperture,
• at least two projections extending from the second longitudinal face of the sealing plate, either side of a central longitudinal area of the sealing plate, where each projection has a height and projects beyond the second longitudinal face to provide a clearance between the second longitudinal face and the radially internal surface, where the clearance is within the range from 0.1 mm to 0.5 mm,
• at least two recesses made in the first longitudinal face and placed close to the two projections, where said at least two recesses are placed opposite the radially external faces of the first and second apertures,
• wherein the recesses and the projections are obtained simultaneously by stamping of the sealing plate, and wherein the sealing plate is substantially flat except where the recesses and projections are located.
