Title:
METHOD AND DEVICE FOR DAMPING VIBRATION OF AIRFOIL OF AIRCRAFT BY OPERATING CONTROL SURFACE
Document Type and Number:
Japanese Patent JPS5984696
Kind Code:
A
Abstract:
To reduce buffeting caused by separation on the wings of an aircraft, a parameter representing the buffeting in amplitude, frequency and phase is measured. The measuring signal is subjected to filtering intended to establish the characteristics of at least one mode of vibration of the wings and, by actuating a control surface according to a non-stationary law, in a localized region the wings, of alternate stresses are generated whose amplitude and phase are automatically determined to dampen one or several modes of vibration of the wings.
