Abstract: A thrust-reversal cowling selectively movable between a retracted position for leaving unchanged the thrust of an aircraft turbine engine, and a deployed position for reversing the thrust of the turbine engine; an electrical actuator of the cowling; a local control module to receive commands from a global control module to control the electrical actuator to move the cowling, these commands including a retraction command and a deployment command; and a connection between the global control module and the local control module for conveying at least one analogue signal. The local control module identifies one among a plurality of predefined ranges of values, in which each analogue signal is located at a given instant, each command being associated with one or more value ranges; and determining the received command as being that associated with the identified range or ranges of values.

Abstract: An electrical control system intended for an aircraft turbojet engine nacelle includes two control modules of a single power module controlling an electric machine and an approval module linking each of the control modules to the single power module. The approval module selectively authorizes the control of the single power module by one of the control modules.

Abstract: A method for de-icing or anti-icing an aircraft portion having at least one piezoelectric element fastened on the inner face of the aircraft portion includes, during a design phase of the aircraft portion, placing the piezoelectric element on an area of the aircraft portion to determine frequencies of resonance and increased dynamic coupling, and during the de-icing or anti-icing of the aircraft portion, the same piezoelectric element is excited according to the natural frequencies of the area.

Abstract: The present disclosure relates to a nacelle for an aircraft turbofan engine and an aircraft that includes a nacelle that includes a supply device for supplying electric power to an electric actuator system allowing movement of a mobile member for deflecting a stream between a first position parallel or substantially parallel to the flow of the stream and a second position allowing the flow of the stream to be deflected so as to modify the path of the stream in one direction and/or the speed of the stream.
