System for controlling the cowl of a turbojet engine nacelle thrust reverser

An aircraft comprising at least two turbojet engines each housed in a nacelle, wherein the nacelle comprises:

• an air inlet forward section,
• a median section surrounding a fan of the turbojet engine,
• an aft section equipped with at least one thrust reverser system comprising at least one mobile cowl which, under action of at least one electromechanical actuation means, is able alternately to move from a closed position in which the mobile cowl provides the aerodynamic continuity of the nacelle, to an open position in which the mobile cowl opens a passage in the nacelle,
• at least one power control unit per turbojet engine able to convert a high voltage electric supply into at least one electric supply towards electromechanical actuation means, each power control unit being located within the nacelle of its respective turbojet engine, and
• at least one drive unit for the power control unit,
• wherein the at least one drive unit receives instructions from an engine controller and is physically distinct and separate from the at least one power control unit and comprises at least one control input and at least one drive output being connected to the power control unit,
• wherein the at least one separate drive unit is common to the at least two nacelles and is located outside the at least two nacelles.
