Device and Method for attenuating at least one rigid body mode and/or at least one elastic mode of an aircraft

摘要

A sensor (27) in the cockpit measures the yawing motion produced by sideways gusts of wind (29) hitting the fin and rudder (38) of the aircraft (22). The yaw signals (31) are transmitted directly to a regulator circuit (33) and a frequency measurement circuit (34). The frequency measurement circuit is connected to the regulator circuit. The regulator circuit in turn sends a feedback control signal (36) to aerodynamic control surfaces (40) especially ailerons (39) and spoilers (37) on the wings (26).
