A containment case (130) for a turbine engine circumscribes an array of rotatable blades and comprises a penetration resistant containment ring (152) and an impact isolator (138a, 138b) extending from the containment ring. The containment case has an impact zone (136) which is the region where any blade fragment which separates from a blade is anticipated to strike the containment case. The containment ring is axially coincident with the impact zone, and the impact isolator is axially spaced from the impact zone. In one embodiment, The impact isolator is a circumferentially extending convolution. During operation, the impact isolator protects the integrity of a connection (139, 141) between the containment case (130) and an adjacent case (62, 64) and reduces the severity of forces transmitted to components (108) mounted on the case.

[ I claim:] [1.] A containment case for a turbine engine, the turbine engine having a flowpath extending therethrough, a rotor including a hub and an array of rotor blades extending radially outwardly from the hub and across the flowpath, the containment case being connectable to an adjacent engine case and having an impact zone, the containment case characterized by:a penetration resistant containment ring axially coincident with the impact zone, andat least one impact isolator extending from the containment ring and axially spaced from the impact zone for protecting the integrity of a connection between the containment case and the adjacent case in the event that a separated blade fragment strikes the containment case.
