Process for producing a turbine blade.

Process for producing a turbine blade (1) in a hollow profile in which a first core element (10) is joined, through several spacers (14) approximately cylindrical, an element of additional core and / or a mold casting, where the cavities (4, 6) left by the core elements (10) in the mold are filled with airfoil material, and in which the openings remaining in the turbine blade (1) after extracting the core elements (10) and the spacers (14), and which are created by the spacers (14) are closed by stopper elements.
