Abstract

Official abstract text for this publication.

A plate closes the main part of a vane in two parts. An internal cavity is closed by the plate. Around a bearing surface of the plate, a groove receives an elastic seal, and the outer edge of the plate extends over the groove to compress the seal and to establish excellent leak proofing. The position of the plate may be guaranteed by centring pins penetrating into holes adjacent to the seal and which it fills when the pins have been removed, which completes the closing of the cavity. The plate has application in particular to stationary gas guide vanes in turbine engines.

First claim

Opening claim text (preview).

The invention claimed is: 1. A turbine engine vane, comprising: a main part containing a cavity and ribs extending into the cavity; and a plate joined to the main part while closing the cavity and while resting on the ribs, wherein the plate is joined to the main part while resting on a bearing surface of the main part, the bearing surface is set back with respect to an outer face of the main part that surrounds the main part, by a region adjacent to an outer edge of the plate, and wherein the outer edge of the plate extends above a groove of the main part which surrounds the bearing surface and is filled by a seal made of elastic material, the seal being compressed by the outer edge. 2. The turbine engine vane according to claim 1 , wherein the seal extends into aligned holes of the main part and of the plate, used to center the plate with respect to the main part and next to the groove. 3. The turbine engine vane according to claim 2 , wherein the aligned holes extend into and in front of the ribs. 4. A method of manufacturing a turbine engine vane comprising a main part containing a cavity and ribs extending into the cavity, and a plate joined to the main part while closing the cavity and while resting on the ribs, wherein the plate is joined to the main part while resting on a bearing surface of the main part, the bearing surface is set back with respect to an outer face of the main part that surrounds the main part, by a region adjacent to an outer edge of the plate, wherein the outer edge of the plate extends above a groove of the main part which surrounds the bearing surface and is filled by a seal made of elastic material, the seal being compressed by the outer edge, and wherein the seal extends into aligned holes of the main part and of the plate, used to center the plate with respect to the main part and next to the groove, the method comprising: introducing, after having laid the plate on the ribs and before fixing the plate onto the main part, centering pins into the aligned holes. 5. A method of manufacturing a turbine engine vane comprising a main part containing a cavity and ribs extending into the cavity, and a plate joined to the main part while closing the cavity and while resting on the ribs, wherein the plate is joined to the main part while resting on a bearing surface of the main part, the bearing surface is set back with respect to an outer face of the main part that surrounds the main part, by a region adjacent to an outer edge of the plate, wherein the outer edge of the plate extends above a groove of the main part which surrounds the bearing surface and is filled by a seal made of elastic material, the seal being compressed by the outer edge, wherein the seal extends into aligned holes of the main part and of the plate, used to center the plate with respect to the main part and next to the groove, and wherein the aligned holes extend into and in front of the ribs, the method comprising: introducing, after having laid the plate on the ribs and before fixing the plate onto the main part, centering pins into the aligned holes.
