ASSEMBLY INCLUDING A REVERSE THRUST DEVICE AND SYSTEM FOR ACTUATING SAID DEVICE

摘要

The invention relates to an assembly including a reverse thrust device (20) and to a system for actuating said reverse thrust device (20), said device (20) including at least one cowl (30) that is translatably mounted in a direction substantially parallel to a longitudinal axis of a nacelle. Said cowl is capable of passing alternately between a closed position, in which said cowl ensures the aerodynamic continuity of the nacelle, and an open position, in which said cowl opens a passage into the nacelle, said passage being intended for a diverted flow. Said cowl (30) is also extended by at least one variable nozzle section (40). Said nozzle (40) includes at least one rotatably mounted panel (41). Said panel (41) is suitable for pivoting towards at least one position that causes a variation in the nozzle section. The actuation system includes an actuation means (60) that is capable of activating the respective translational and rotational movement of the cowl (30) and the panel (41) of the nozzle (40). Said actuation system is characterized in that it also includes a downstream locking means (80) for the nozzle (40) and the cowl (30). The downstream locking means (80) includes at least two reversible states, one of said states being a locked state in which the downstream locking means (80) is suitable for locking the panel (41) of the nozzle (40) into a position for varying the section for outputting the nozzle with the cowl (30).
