    摘要: The invention relates to a method for mounting vanes (10) in the periphery of a turbine engine disc (12), the disc (12) comprising cavities extending alternately with teeth, the vanes (10) respectively comprising: roots to be inserted into the cavities, shrouds (26), and blades (24) connecting the roots to the shrouds. According to the invention, the method comprises the following steps: (a) positioning the vanes (10) such that the root of each blade is axially facing one of the cavities of the disc; (b) providing a mounting tool (50) comprising a tip (40) with a shape partially matching the shroud (26) of one of the vanes; (c) engaging the tip (40) of the mounting tool (50) with the shroud (26) of the vane; (d) pivoting the shroud (26) of the vane by rotating (54) the mounting tool (50); and (e) axially inserting the root of the vane into the cavity of the disc.

    摘要: The invention relates to a method for manufacturing a turbine engine blade (25) comprising a pressure side and a suction side separated from one another by an inner space for the circulation of cooling air, said blade (25) comprising a tip (S) with a closing wall (29) joining the pressure side and suction side walls in the region of this tip (S) in order to define a well shape, said closing wall including through-holes. The closing wall (29) obtained by moulding has a considerable nominal thickness with pits (36, 37) locally reducing this thickness at each through-hole in order to facilitate the removal by chemical etching of alumina rods defining said holes. Since the closing wall (29) thus has a large nominal thickness, it can then be machined in order to form raised patterns or complex shapes inside the well.
