A yaw damper is a device used on many aircraft (usually jets and turboprops) to damp (reduce) the rolling and yawing oscillations due to Dutch roll mode. It involves yaw rate sensors and a processor that provides a signal to an actuator connected to the rudder. The use of the yaw damper helps to provide a better ride for passengers, and on some aircraft is a required piece of equipment to ensure that the aircraft stability remains within certification values.
Famous quotes containing the word damper:
“The shy man does have some slight revenge upon society for the torture it inflicts upon him. He is able, to a certain extent, to communicate his misery. He frightens other people as much as they frighten him. He acts like a damper upon the whole room, and the most jovial spirits become, in his presence, depressed and nervous.”
—Jerome K. Jerome (1859–1927)
