A Simple Method for Calculating the Characteristics of …

A simple method for calculating the characteristics of the Dutch roll motion of an airplane is obtained by arranging the lateral equations of motion in such form and order that an iterative process is quickly convergent. Primary effects of variation of the important stability derivatives on the period and damping can be seen more clearly from the iterative method than from the fourth-order

Dutch Roll, the Quintessential Stick and Rudder …

The Dutch roll is the quintessential stick and rudder pilot’s maneuver. The Dutch roll exemplifies adverse yaw, and it requires proper rudder pressure to counteract that yaw. The maneuver is a series of simple wing rocks

 · Controlling the Dutch Roll Fortunately, as we mentioned before, this is a model of an airplane with no control system. Based on this mathematical model, engineers design and implement a control algorithm called a yaw damper that automatically moves the rudder back and forth and compensates for this phenomenon.

Therefore if you have a problem with Dutch roll, decrease the slip-roll coupling and increase the long-tail slip effect, for instance by making the tail boom longer and reducing the rudder area. As a rule of thumb, you can tell just by looking at a short-coupled airplane that it will have a problem with underdamped Dutch roll.
