Abstract
A bearing arrangement of a gas turbine engine includes a first bearing supportive of a shaft, a second bearing axially offset from the first bearing, a first bearing support extending from a bearing housing to the first bearing to support the first bearing and a second bearing support extending to and supportive of the second bearing. One or more radial bearing supports include a plurality of radial spokes extending between the bearing housing and the second bearing. The plurality of radial spokes are configured to buckle under compression when radial loads at the second bearing exceed a predetermined threshold. At least one destabilizer is secured to the second bearing and is configured to contact at least one radial spoke of the plurality of radial spokes upon failure of the first bearing support to reduce the predetermined threshold sufficiently to initiate buckling of the plurality of radial spokes.
