AOA Vane Test Bench

AOA Vanes are used to measure the angle of attack of an aircraft. An angular sensor of the RVDT senses the angular position of the vane with respect to the fuselage reference line. The angle of attack calibrator provides for calibration of the RVDT’s. The angular position of the vane can be set to any angle from –45 deg to +45 deg and this angle is sensed by a precision encoder, which has an accuracy of 0.03 deg The relative outputs of the four RVDT’s are displayed directly in digital read outs with a resolution of 0.1deg. Direct calibration of the AOA is thus rendered extremely simple.
