Abstract
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.
