Support system having shape memory alloys

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

• a load-bearing unit comprising a first flange;
• a frame supporting the load-bearing unit, the frame comprising a second flange;
• an axial bolt connecting the first flange and the second flange;
• a first super-elastic shape memory alloy component in contact with the first flange;
• and
• a second super-elastic shape memory alloy component in contact with the second flange, wherein the first super-elastic shape memory alloy component is in the form of a gusset, a flange, or a combination thereof, and the second super-elastic shape memory alloy component is in the form of a gasket seal, and wherein the first and the second super-elastic shape memory alloy components are configured to deform when a load exerted by the axial bolt exceeds a threshold load value of the axial bolt.
