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: The invention relates to an assembly (601) which comprises a front frame (602) of a thrust reverser structure of an aircraft nacelle and at least one cascade (603). The assembly is characterized in that, when the cascade is fixed to the frame, the axial distance (L) that separates the first blading (605) upstream of the cascade from a covering area (606) between the extension of the cascade and the front frame is greater than or equal to once the mean height (h) of the cascade.
