Rotor support system with shape memory alloy components for a gas turbine engine

A rotor support system for a gas turbine engine, the gas turbine engine comprising a support frame, the rotor support system comprising:

• a bearing assembly comprising a first bearing assembly and a second bearing assembly spaced axially apart from the first bearing assembly, wherein the first bearing assembly includes a first bearing and a first outer bearing housing extending radially outwardly from the first bearing, and wherein the second bearing assembly includes a second bearing and a second outer bearing housing extending radially outwardly from the second bearing;
• a load reduction member configured to be coupled between the bearing assembly and the support frame of the gas turbine engine, the load reduction member including a fuse portion configured to fail when a load transmitted through the load reduction member exceeds a predetermined load threshold;
• and
• a load recoupling member provided between the bearing assembly and the support frame, the load recoupling member being formed from a super-elastic shape memory alloy that allows the load recoupling member to undergo recoverable deformation without failing when the fuse portion fails such that the load recoupling member maintains a mechanical connection between the bearing assembly and the support frame,
• wherein the first and second outer bearing housings are formed from a super-elastic shape memory alloy that allows the first and second outer bearing housings to undergo recoverable deformation without failing when the fuse portion fails.
