INTERMEDIATE CASING OF AIRCRAFT TURBOMACHINE INCLUDING STRUCTURAL CONNECTING ARMS WHICH PERFORM SEPARATE MECHANICAL AND AERODYNAMIC FUNCTIONS

摘要

A structural connecting arm for an intermediate casing of an aircraft turbomachine with a ducted fan, wherein the arm is configured to connect a hub and an outer ferrule of the casing, and including an aerodynamic outer surface manufactured such that the arm also forms an outlet guide vane. Multiple metal ties extend in the longitudinal direction of the arm, together with a shell made from composite material surrounding the ties and forming the aerodynamic outer surface.
