    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: A variable vane control system for controlling the angle of rotation of a circumferential row of variable vanes of a gas turbine engine. The control system includes a mechanical linkage operable to rotate the variable vanes, one or more actuators for operating the linkage and one or more position sensors for detecting the respective actuation positions of the one or more actuators. The control system further includes a linkage position signalling switch for signalling that the mechanical linkage is at a calibration position corresponding to a predetermined rotation angle of the vanes. The control system further includes a controller for controlling the one or more actuators and thereby controlling the angle of rotation of the vanes, based on the detected actuation positions which the controller correlates with vane rotation angle. The controller further corrects the correlation between the detected actuation positions and vane rotation angle on receipt of a signal from the linkage position signalling switch indicating that the mechanical linkage is at the calibration positionvanes.

    Abstract: A system for moving an aircraft thrust reverser component includes a power drive unit, a thrust reverser actuator assembly, and a tertiary lock system. The power drive unit is operable to rotate and supply a rotational drive force. The thrust reverser actuator assembly receives the rotational drive force from the power drive unit and moves the thrust reverser component between a stowed position and a deployed position. The tertiary lock system selectively engages and disengages the thrust reverser component and includes a tertiary lock power unit, an electromechanical tertiary lock assembly, and a voltage limiting circuit. The voltage limiting circuit limits the voltage magnitude of a control signal supplied to the tertiary lock assembly to a predetermined value.
