The 1/50th scale NFAC model was designed to closely simulate the full-scale NFAC facility and test aerodynamic characteristics of models. The goal of this project was to disassemble, refurbish, and reassemble the six 10 HP motors that power the model's fan drive system, as they had not been serviced in several years. This involved cleaning, testing, balancing, and replacing bearings on the motors. An unrefurbished motor was tested as a baseline, showing structural vibrations due to imbalance. Finally, the refurbished motor will be reassembled and tested, with the aim to refurbish all motors and fully reassemble the 1/50th scale NFAC model.
