ABSTRACT:
An assembly is disclosed for automatically balancing thrust on the rotor of a gas turbine engine. An annular chamber axially positioned relative to the rotor is adapted to receive pressurized hydraulic fluid and apply it to the rotor. The force thereby applied to the rotor is regulated by sensing changes in axial rotor thrust and delivering hydraulic fluid to the chamber at a pressure sufficient to balance axial forces acting on the rotor.
