An alternative system for damping the dutch roll mode in an aircraft is provided using roll control surfaces. Classical yaw dampers for the dutch roll mode utilize the yaw control surfaces such as a rudder to dampen the dutch roll mode oscillations. An alternative damper is described that utilizes roll control surfaces such as spoilers or ailerons to dampen the dutch roll mode.
1. A method for damping the dutch roll mode in an aircraft having a roll control surface, comprising the steps of: measuring at least one parameter of the motion of the aircraft;applying a washout filter to the at least one parameter of motion to remove low frequency signals from the measured parameter of motion of the aircraft;calculating a damping signal that is proportional to the at least one parameter of the motion of the aircraft as modified by the washout filter; andactuating the roll control surface in proportion to the damping signalwherein the ...
