Angle of attack sensor using ball mouse encoder wheel

Abstract

In this paper, a new kind of Angle of Attack (AOA) sensor has been designed and calibrated, which is different from the conventional AOA sensor. The sensor is developed using a ball mouse encoder wheel and two Infrared (IR) modules. The system provides a low cost solution to angle of attack measurements with good precision and accuracy. The sensor has been developed for measuring the angle of attack of the test pieces placed inside a Closed Subsonic Wind-Tunnel.
