ABSTRACT:
A process for manufacturing a blade of a turbomachine using the lost-wax moulding technique, where the blade includes a first central longitudinal cavity and at least one second longitudinal cavity together forming a cooling circuit and communicating with each other at one longitudinal end via a transverse channel. The process includes manufacturing first and second cores corresponding to the cavities, where the two cores each have an end portion, by which they are connected together by an assembly of the mortise and tenon type. The assembly of the two cores is then positioned in a shell mould and the metal poured into the mould.
