Abstract
A bearing arrangement of a gas turbine engine includes a first bearing and a second bearing axially offset from the first bearing. A first bearing support extends from a bearing housing to the first bearing to support the first bearing, and a second bearing support extends from the bearing housing to the second bearing to support the second bearing. One or more radial bearing supports including a plurality of radial spokes extend between the bearing housing and the second bearing. Each spoke extends from a spoke base to a spoke tip. A raised pedestal is positioned at a contact point of each spoke tip, and at least one destabilizer is secured to the second bearing and is configured to contact at least one radial spoke when the predetermined threshold is exceeded to initiate sliding of the plurality of radial spokes from their respective raised pedestal.
