초록

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.

청구항

Method for reducing the stresses due to buffeting of an aircraft wing, said method comprising: continuously measuring at least one parameter representative of the amplitude, frequency and phase of buffeting in an aircraft wing; generating an electrical signal representative of said parameter; subjecting said electrical signal to filtering for isolating the amplitude, frequency and phase of at least one mode of vibration of wing caused by buffeting; computing the value and variation of alternate forces to be applied in one localized region of the wing for...
