Turbomachine blade including an external shell including a pressure-side wall and a suction-side wall delimiting between them an interior volume, an insert arranged in the interior volume so as to form an air passage between the insert and the external shell; and at least one breakable joining portion, connected on the one hand to the insert and on the other hand to the external shell; wherein one at least of the mechanical breaking resistance of the breakable joining portion, the mechanical breaking resistance between the breakable joining portion and the external shell and the mechanical breaking resistance between the breakable joining portion and the insert is less than the mechanical breaking resistance of the external shell and the mechanical breaking resistance of the insert.

Turbomachine blade, turbomachine and method for manufacturing the blade

A stator vane of a turbine of a gas turbine engine, including an outer platform and an inner platform between which there extends an outer wall forming an outer skin, wherein it includes an inner wall, forming an inner skin, facing the outer wall so as to define an inter-skin cavity between the outer wall and the inner wall, the inner wall including a plurality of cooling orifices for impingement cooling of the outer wall, the outer wall and inner wall being produced by additive manufacturing.

Turbine stator vane comprising an inner cooling wall produced by additive manufacturing

The present disclosure relates to a blade of a guide vane assembly of a turbomachine fitted with a cooling system, generally including an insert arranged inside an internal cavity of said blade, connected to a cooling air inlet of the blade and designed to cool the surface of the internal cavity of the blade, and a bleed device configured to bleed some of the cooling air inside the insert and designed to send this bled cooling air to a central hub of the turbomachine. The bleed device of the blade may further include a bleed head arranged in the internal cavity of the blade and passing through an opening of the insert, and configured to bleed some of the cooling air inside the insert.
