Brakes and Feedback Devices

Asymmetry Brakes are used to prevent flap movements in the event of mechanical failure in the transmission or a runaway condition.

RVDTs are a type of sensor used provide motion feedback to the control system.

Moog’s heritage includes position sensing and braking devices.  Common features of these devices include rotary variable differential transformer (RVDTs) and asymmetry and overspeed arresting brakes.  Moog also provides slat and flap skew detection systems that include lanyard-style linear variable differential transformer (LVDT) technologies.
