Abstract:
1. A control device for aircraft for reducing the turbulence and gust influences on the flying characteristics, comprising: a sideslip angle sensor for determining the instantaneous sideslip angle (β); a bank angle sensor for determining the instantaneous bank angle (Φ); and controller for generating an additional incidence angle drive signal for control surfaces on said aircraft which generate an air force as a function of the instantaneous bank angle (Φ) and sideslip angle (β), said additional incidence angle drive signal being provided to be added to a main drive signal for the control surfaces, wherein the control device determines the drive signal as a function of a component (α where Φ is the bank angle, {dot over (H)} is the vertical velocity of the aircraft, V is the airspeed of the aircraft with respect to the surrounding air, θ is the longitudinal attitude angle of the aircraft, α is the angle of attack, q is the pitch rate of the aircraft, r is a function of the ratio of the vertical velocity {dot over (H)} to the airspeed V.
