Abstract
A mid-turbine frame has a pre-stress design and is connected to an engine casing of a jet turbine engine to distribute a first load from a first bearing and a second load from a second bearing. The mid-turbine frame includes at least one torque box, a first bearing, a second bearing, and at least one strut. The torque box absorbs the first and second loads. The first bearing cone connects the first bearing to the torque box and the second bearing cone connects the second bearing to the torque box. The strut connects the torque box to the engine casing.
