Abstract
A forward outer diameter ring includes a flowpath ring extending circumferentially about a central axis and extending axially from a first end to a second end relative to the central axis. The second end of the flowpath ring is axially aft of the first end. A hoop stiffener is connected to the second end of the flowpath ring and extends circumferentially around the second end of the flowpath ring. The hoop stiffener includes a first stiffener end connected to the second end of the flowpath ring and a second stiffener end axially aft of the first stiffener end. The hoop stiffener further includes tabs formed in the second stiffener end. The tabs are circumferentially spaced apart from one another and connect the case segments to the second stiffener end. The case segments are circumferentially arranged about the central axis relative one another.
