A calibration rig has been designed and constructed at the NASA Ames Research Center to calibrate the multi-component rotor balance in the Large Rotor Test Apparatus. The rotor balance capacity is 52,000 lbs thrust, 15,000 lbs shear force, and 125,000 ft-lbs of roll and pitch moment. The rotor shaft flex-coupling has a torque capacity of 164,800 ft-lbs. Eleven hydraulic actuators with in-line load cells, operating in a tension mode only, are used to apply the calibration loading. The Large Rotor Test Apparatus, the rotor balance, and the design and operation of the calibration rig are described.
