Adverse Yaw
Adverse Yaw is a flight dynamics phenomenon observed in fixed-wing aircraft, where the aircraft yaws in the opposite direction to a roll. This is primarily caused by the difference in lift and drag forces acting on the wingtips during a roll maneuver. When an aircraft rolls, the lift on the wing that is rising decreases, while the lift on the wing that is descending increases. This difference in lift creates a yawing moment in the opposite direction of the roll. Additionally, the increased lift on the descending wing also increases the drag on that wing (due to induced drag), which further contributes to the yawing moment. Adverse yaw can be counteracted by the use of coordinated rudder inputs, which is a fundamental skill in aircraft piloting. In aerospace engineering, understanding and managing adverse yaw is crucial in the design and control of aircraft, particularly in the design of control systems and flight control surfaces.
