摘要

The element has a blower (2) provided with a casing (7). An external ring (8) of an intermediate casing forms a monoblock single piece (13) made of composite material with the casing of the blower. The external ring is directly connected to outlet guide vanes (5) located in downstream of revolving paddles (4) of the blower. A radial stiffener (14) is arranged on external perimeter of the single piece. The stiffener comprises a fixing point (17) of secondary equipments (16). A deviation edge of a thrust reverser is integrated in the single piece. An independent claim is also included for a method for manufacturing a blower element of a turbojet.
