Abstract
An exhaust casing hub includes a hub center, and an upstream flange and a downstream flange arranged on either side of the hub center. Each flange is terminated by a rim. A plurality of cuffs are arranged on the hub center so as to form an angle from the tangent toward the radial direction of 10° to 80° , preferably 15° to 75°. At least one rib is formed at the base of each cuff below a critical stress region in the cuff. The rib is joined to the downstream flange by a downstream end and to the upstream flange by an upstream end.
