Abstract
A bearing support apparatus for a gas turbine engine, including: a first annular member; a second annular member disposed within the first annular member; first and second axially spaced-apart rolling-element bearings disposed between the first and second annular members so as to enable relative rotation of the first and second members; a first spring element mounting the first bearing to the first member; and a second spring element mounting the second bearing to the first member through the first spring element, such that the first and second bearings are physically supported in series relative to the first member.
