Abstract: In this paper, the device for measurement model angle of attack in wind tunnel T-32 is presented. It is consisted of sensor and indicator. Sensor gives voltage on its output dependence of angle. Indicator is a device which is developed in the Military Technical Institute. It is connected to the sensor and measures sensor’s output voltage. Firstly, the indicator does the analog processing sensor’s output voltage. After that, indicator does A/D conversion and digital processing measured voltage. At the end, indicator shows measured voltage and angle on its LCD display. Information of the precise model angle of attack is very important in wind tunnel testing because it makes influence on all the other measurements in wind tunnel.

Keywords: Sensor, indicator, measurements, subsonic wind tunnel.
