AUBE DE TURBINE A PALE CREUSE EN MATERIAU COMPOSITE, TURBINE OU COMPRESSEUR AYANT UN DISTRIBUTEUR OU REDRESSEUR FORME DE TELLES AUBES ET TURBOMACHINE LES COMPRENANT

摘要

A turbine engine vane is made of composite material comprises a hollow airfoil with an internal passage extending along its entire length, an inner platform, and an outer platform. The airfoil is extended on the outside of the outer platform by an upstream attachment portion and a downstream attachment portion for mounting the vane in a casing. The attachment portions are formed by an attachment extending from the outer longitudinal ends of the pressure side wall and the suction side wall of the airfoil with continuity of the fiber reinforcing texture of the composite material between the walls and the attachment tabs.
