A complete in-house design, development and manufacturing capability exists to provide thrust reverser actuation systems, including mechanical synchronous locks, and cowl door opening systems, nacelle actuation systems range from simple hydraulic jacks to more complete ball screw actuators, in both, synchronous travel is essential.

The advent of ever larger engines has led to cowl doors with powered opening systems becoming mandatory. Systems available include more complex self-contained hydraulic power pack to the simpler externally powered actuators.

Goodrich can be relied upon to provide lightweight, highly reliable actuation systems for any civil transport aircraft.

The thrust reverser actuation system deploys and stows the translating cowls on landing, after touchdown, in response to commands from the FADEC and aircraft electrical circuits. 

To prevent inadvertent in-flight deployment each surface usually has three separate locking devices with at least one lock independently controlled

• Thrust reverser redirects the mixed fan airflow outward and forward 
• Three separate safety systems prevent inadvertent deployment
• Unlock conditions are detected and flagged to the FADEC and the pilot.
• Easier maintenance through improved fault isolation
