Abstract
The Wing Rock phenomenon is characterized by an undesirable rotational oscillation, mainly on the aircraft's rolling, axis that occurs in airplanes when they are at relatively low flying speeds and with a high angle of attack. The present work intends to study the behavior of this phenomenon in aluminum rectangular plates for two distinct aspect ratios (AR) using a wind tunnel. Rectangular aluminum plates with AR of 2 and 4 are tested with a thickness of 0.5 mm. The oscillations were measured using an Arduino Uno board and an MPU-6050 accelerometer that can measure the acceleration angles around the x, y, z axis of the sensor. Variation of the rolling angle due to Wing Rock phenomenon and it was studied and it was observed that the roll angle amplitude increases with AR, which is in agreement with data published in the literature. Thus, the increase in AR leads to an intensification of the swing amplitude of the wing roll angle.
