<p>The duct has a cylindrical outer wall (5) and a cylindrical inner wall extending one inside another and delimiting an annular space for secondary air flow of a turboshaft engine. The outer wall includes a rectangular opening (22) closed by a trap door (24) fixed in a removable manner. A reinforcement unit i.e. brace (26), extends in the opening, and is configured to transmit efforts induced by the turbo shaft engine during operation. The reinforcement unit includes an arm (28) connecting a contour of the opening in attachment points (29). An independent claim is also included for a method for assembling a reinforcement unit on a fan duct.</p> |
