Abstract (en)
Apparatus and method of balancing thrust bearing load on a rotor thrust bearing (40) employ a first thrust balance piston cavity for exerting an aft directed thrust balancing force and a second balance piston cavity (42) for exerting an independently controlled forward directed thrust balancing force to allow flexible and wide range balancing of thrust load on the rotor thrust bearing (40).
