    Abstract: A journal bearing provides lubrication to planetary gears during windmilling operation of a fan section. A primary oil pump provides oil from an oil supply during driven operation of the fan and a secondary oil pump driven by a generator provides oil during windmilling operation of the fan. The generator acts as a dynamic brake when the aircraft is grounded to prevent windmilling. A switch selects between the primary and secondary oil pump and controls the brake application.

    Abstract: In an open state of a valve, when a valve outside sleeve is rotated in the rear portion of a housing, a valve inner sleeve is moved forward to close a fluid channel, thus stopping supply of compressed driving air. Simultaneously, a front end of the valve outside sleeve is moved forward while it abuts against the rear surface of a retainer. Therefore, brake rods biased by compression coil springs are also moved forward, and front surfaces of the brake rods are abutted against a brake disk to effect braking, thereby immediately stopping rotation of a rotor. The urging force applied on the brake disk is the compression force of the compression coil springs.
