Claim:
1. An online real time turbine engine rotor balancing system, comprising: a rotor having a rotation axis; a balancing ring perpendicular to the rotational axis and establishing a balance plane, said balancing ring including a radially oriented bore establishing a displacement path in the balance plane; a selectively displaceable balancing weight coupled to the rotor and adapted for being displaced along the displacement path; a motor coupled to the balancing weight and the rotor, for selectively displacing the balancing weight along the displacement path; a turbine engine rotor vibration monitoring system for monitoring rotor vibration in real-time; and a control system coupled to rotor vibration monitoring system and the motor, for determining in real time a desired balance weight displacement position to counteract the monitored rotor vibration and selectively causing the motor to displace the balancing weight to the desired displacement position along the displacement path.
