How is a yaw damper used to overcome Dutch roll in swept-wing aircraft?

A yaw damper is an essential component in swept-wing aircraft designed to enhance stability and control during flight. Specifically, it addresses the phenomenon known as Dutch roll, which is a type of oscillation that occurs when the aircraft simultaneously yaws and rolls.

In essence, a yaw damper works by automatically detecting these oscillations and applying corrective inputs to the rudder and ailerons to counteract them. When the aircraft begins to yaw one way, the yaw damper kicks in and applies rudder input to bring the aircraft back on track. By doing so, it smooths out the oscillations, preventing them from escalating and helping to maintain a stable flight path.

Understanding the mechanics of yaw and roll is crucial when discussing how a yaw damper functions. While the other options mention adjustments to lift characteristics, throttle settings, or airflow management, these do not directly relate to how Dutch roll is primarily controlled. The yaw damper explicitly focuses on stabilizing yaw motions and roll interactions, making it a critical tool for ensuring a smooth flying experience in swept-wing aircraft.
