Abstract (en)

[origin: WO2006086945A1] The invention relates to a bearing arrangement, especially for a gas turbine aircraft engine, said arrangement comprising a first bearing ring (11) which is fixed and on the stator side, and a second bearing ring (12) which is rotatable and on the rotor side. Rolling bodies (13) are arranged between the stator-side bearing ring (11) and the rotor-side bearing ring (12). Transducers for determining the position of the stator-side bearing ring (11), and actuators (21) for influencing the position of the stator-side bearing ring (11), are associated with the stator-side bearing ring (11).
