System for actuating a movable structure of a thrust reverser of an aircraft, thrust reverser and jet engine comprising such a system

An actuator system for actuating a cover of an aircraft thrust reverser, the system comprising:

• a first electric motor;
• a first actuator arranged in the proximity of the first motor in order to be driven by the first motor;
• a second actuator and a first flexible transmission shaft that is connected firstly to the second actuator and secondly to the first motor so that the second actuator is arranged to be driven by the first motor;
• a second electric motor;
• a third actuator arranged in the proximity of the second motor in order to be driven by the second motor;
• a fourth actuator and a second flexible transmission shaft that is connected firstly to the fourth actuator and secondly to the second motor so that the fourth actuator is driven by the second motor;
• and
• control means for controlling the motors to synchronize drive of the first actuator, of the second actuator, of the third actuator, and of the fourth actuator by means of the two motors;
• the system further including a third flexible transmission shaft that is connected firstly to the second actuator and secondly to the fourth actuator in such a manner that each actuator is movable by each of the two motors.
