Patent ID: 6915989

Claim:
A system for controlling deformation of an aircraft during flight, comprising: a receiver coupled to at least one aircraft sensor to receive an input indicative of excitation of a torsional mode of a body of an aircraft about a longitudinal axis of the aircraft during flight; and a processor coupled to the receiver, the processor being further coupled to a first elevator surface on a first side of the longitudinal axis and a second elevator surface on a second side of the longitudinal axis, the processor being configured to: direct a first output signal to the first elevator surface to deflect the first elevator surface in a first direction; simultaneously direct a second output signal to the second elevator surface to deflect the second elevator surface in a second direction opposite the first direction to actively counter excitation of the torsional mode of the body of the aircraft; and while actively countering excitation of the torsional mode of the body of the aircraft, direct a third output signal to the first and second elevator surfaces to move the first and second elevator surfaces in the same direction to control a pitch attitude of the aircraft.
