摘要

Aerodynamic duct assembly for a turbomachine, assembly and repair methods for this assembly An aerodynamic duct assembly comprises a casing (10) having an inner face capable of carrying at least one fixed blade (4), and a duct wall (20) intended to face the moving vanes (3), the vein wall (20) being fixed to the housing (10) so that the housing (10) and the vein wall (20) together form a vein portion aerodynamic. The housing (10) has a groove (10U) in which an axial end portion (21) of the vein wall (20) is received, two walls facing said groove (10U) each having a first through hole (11, 12), and said axial end portion (21) has a second through hole (22) facing the first through holes (11, 12). A threaded locking element (30, 30 ", 30") is received in the through holes (11, 12, 22). Figure for the abstract: Fig. 2.
