A three-component electronic wind-tunnel balance installed in a 3.5 by 5.0 foot subsonic tunnel was evaluated for system problem areas. The nonlinear output of the reluctance gage transducers was analyzed and linearized using diode function-generating circuitry. A static calibration was conducted to confirm the linearity of the circuits. Evaluation of the balance system under operating conditions pointed out other areas for future investigation. Author
