Abstract
A seal configuration for an aircraft engine includes a ring shaped sealing component defining an axis. A carrier is disposed radially outward of the ring shaped sealing component and supports the ring shaped sealing component. A housing includes a shroud portion. The shroud portion fully surrounds the carrier and is maintained in a static position relative to the carrier via a bellows spring and a plurality of rotation inhibiting features. Each rotation inhibiting feature in the plurality of rotation inhibiting features includes a tab protruding radially outward from the carrier and received in a slot intruding into the shroud portion.
