REDUCING GUST LOADS ACTING ON AN AIRCRAFT

摘要

The invention relates to a device and a method for reducing gust loads acting on an aircraft. The aircraft has at least one aerodynamic control surface which can be moved by at least one actuator, and a flight control system provides reference variables Xsoll and/or {dot over (X)}soll to actuate the actuator. Xsoll indicates a target position or a target force or a target moment and {dot over (X)}soll indicates a change over time of Xsoll. The device includes: a sensor system, which determines forces Fext,Boe acting from outside on the control surface and produced by gusts; and a regulator for regulating the actuator on the basis of: Fext,Boe, the reference variables Xsoll and/or {dot over (X)}soll and control variables X and/or {dot over (X)} generated by the actuator and detected by a sensor system, wherein the regulator has a regulation behavior with which the forces Fext,Boe produced by gusts are compensated.
