  • Two-brake torque limiting device
    Patent number: 6659398
    Abstract: The apparatus of the invention enables a two-brake torque limiting device to fix the position of one or more flaps and/or slats on an airplane wing when unplanned or abnormal conditions exist. The two-brake torque limiting device may include a trigger brake, a lock down brake, and a speed-increasing device. The trigger brake may use an electromagnetic brake to apply a braking force to the lock down section. The braking force transferred to the lock down section from the trigger section may be transferred through a speed-increasing device. The speed-increasing device allows for the use of a small and a lightweight electromagnetic brake. The invention also provides a method for reducing asymmetry in the wings of an aircraft using an asymmetry detection device, using a trigger brake, using a speed-increasing gear, and using a lock down brake.
