Abstract
A device that is capable of actuating at least two cowls of a thrust reverser. The device includes for each cowl, (a) at least two actuators suitable for opening and closing the cowl, (b) at least one slave flexible transmission shaft establishing mechanical connection between the two actuators of the cowl and (c) at least one mechanical coupling device associated to the at least one slave flexible transmission shaft. The device is further comprised of one motor, and at least two master flexible transmission shafts, each master flexible transmission shaft establishing mechanical connection between the motor and one respective mechanical coupling device. Upon rotation of the electrical motor, the master flexible transmission shafts are actuated, which causes actuation of the mechanical coupling devices, which causes actuation of the slave flexible transmission shafts and thereby the extension or retraction of the actuators.
