A relatively less complex segmented spring mounted under the bearing and damper or the same configuration segmented spring mounted on either side of the bearing and damper serves to center the shaft of a rotor of a gas turbine engine and is characterized as being simple, occupying minimum space, but

A relatively less complex segmented spring mounted under the bearing and damper or the same configuration segmented spring mounted on either side of the bearing and damper serves to center the shaft of a rotor of a gas turbine engine and is characterized as being simple, occupying minimum space, but being capable of maintaining an adequate fatigue stress margin.

For a shaft having bearing means being supported in operation by a fluid damper having a uniform circumferential sealed fluid chamber being supplied pressurized fluid circumscribing said bearing means, a segmented ring-like spring mounted adjacent to and in juxtaposed relationship with said fluid damper and being in serial load relationship so as to center said shaft and providing support for increased loads that overcome the support of said fluid damper, a housing having an annular surface supporting said segmented ring-like spring and said fluid damper, each segment of said segment having a pair of outwardly protruding loads disposed at either end thereof and an inwardly protruding load adapted to bear against said bearing means and said annular surface, each of said segments being disposed intermediate into ends resilient and flexible to support said increased loads and each segment disposed in end-to-end relationship to define a ring circumscribing said bearing means and said fluid damper.
