van Aken, J. M., Peterson, R. L. and Freedman, C. J., "Calibration Results of the NASA Ames Rotor Test Apparatus Steady/Dynamic Rotor Balance," Proceedings of the American Helicopter Society Aeromechanics Specialist Conference, San Francisco, CA, January 1994, Paper No. 4.4.

Keywords: Rotor balance, Rotor loads, Balance calibration, Dynamic response

Abstract: The NASA Ames Rotor Test Apparatus was recently modified to include a steady/dynamic rotor balance. The calibration procedures and data reduction process to obtain static and dynamic calibration coefficients are discussed. Verification of the dynamic calibration procedures and the data processing for the low frequency range was accomplished by means of a hub imbalance run. Representative results of the balance predictions for the hub imbalance forces and moments are provided.
