METHOD OF PRODUCING A HIGH-PRESSURE TURBINE BLADE COMPRISING A CAVITY UNDER A SQUEALER TIP

The invention relates to a method for manufacturing a vane (11) of a turbine engine comprising a pressure-face wall (14) and a suction-face wall (15) spaced apart from one another, this vane (11) comprising a tip (S) with:a bottom wall (18) extending from the pressure-face wall (14) to the suction-f...

Zusammenfassung:	The invention relates to a method for manufacturing a vane (11) of a turbine engine comprising a pressure-face wall (14) and a suction-face wall (15) spaced apart from one another, this vane (11) comprising a tip (S) with:a bottom wall (18) extending from the pressure-face wall (14) to the suction-face wall (15), each of which comprises a free edge (19, 21) extending beyond this bottom wall (18) to delimit, together with this bottom wall (18), a squealer shape (B);a partition wall (22) extending from the pressure-face wall (14) to the suction-face wall (15) and spaced apart from the bottom wall (18) to delimit, together with this bottom wall (18), a cavity (C) under the squealer tip;the method including:a moulding step to form at least the pressure-face wall (14), the suction-face wall (15) and the partition wall (22);-a step of forming the bottom wall (18) using an additive manufacturing method by adding metal material.
