HYDRAULIC CONTROL SYSTEM FOR A THRUST REVERSAL DEVICE

摘要

The present invention relates to a hydraulic control system for a thrust reversal device installed on a jet engine nacelle and combined with a nozzle variation device, which includes at least one mobile cowl translated by a plurality of mutually synchronised single-action actuators (1d, 1g), said hydraulic control system including at least one unit (100d, 100g) for controlling the cylinders according to a variable nozzle mode, and at least one unit (200) for controlling the cylinders according to a thrust reversal mode, characterised in that the control system includes at least one additional regulation unit (400) hydraulically interconnecting the cylinders and including a plurality of control valves (401, 402).
