Abstract
Size problems and large power requirements for operating a no-back are avoided in a pilot operated no-back including a housing (10) journaling input and output shafts (12, 18). A brake disc pack (32) is disposed within the housing (10) and is compressible to prevent rotation of the output shaft (18). A ball ramp mechanism (24) has a rotary input plate (26) and a rotary output plate (28), the latter being axially movable to compress the brake disc pack (32). A selectively operable electric pilot brake (70) is provided to retard rotation of the output plate (28) but allow motion via opposing load if disengaged.
