A device comprising a plurality of sensors arranged on an aircraft and configured to measure input data, an avionics computer configured to determine, based on the input data, at least one control command for at least one control surface of the aircraft by using a control law comprising at least one gain value, the control law being configured to obtain a control command making it possible to generate a flutter mode on at least a part of the aircraft, and a control system configured to control the control surface of the aircraft so as to generate the flutter mode by using the control command determined by the avionics computer.

Device and method for generating flutter on at least a part of an aircraft

An actuating system comprising a hydraulic actuator provided with a cylindrical cavity containing a piston configured to slide within the cylindrical cavity and a rod. The piston separates the cylindrical cavity into a first actuating chamber and a second actuating chamber. A first servo valve comprises a sheath including a first slider configured to slide within a cavity of the sheath on the basis of command signals from a command system. The cavity of the sheath comprises a first command chamber and a second command chamber on either side of the first slider. The first actuating chamber is fluidically connected to the first command chamber, and the second actuating chamber is fluidically connected to the second command chamber.

System for actuating a control surface of an aircraft

A method and device for reducing actual loads generated on airplane by an aerodynamic disturbance is provided, the device including means for determining a load exceeding envelope and means for determining deflection orders of airplane control surfaces to reduce loads applied on the latter, when the airplane flies inside the load exceeding envelope. More specifically, a flight envelope of the airplane is determined and used with theoretical loads applied to the aircraft to produce the load exceeding envelope based on couples of the flight envelope with theoretical loads that equal or exceed a load threshold.
