Abstract: A turbine engine includes a turbo-engine, a fan including a plurality of fan blades that rotate about a longitudinal centerline axis, a rotational component coupled to the fan, a fluid circuit for supplying a fluid to the turbine engine, and a hydraulic fan brake in fluid communication with the fluid circuit. The hydraulic fan brake includes a hydraulic actuator fluidly coupled to the fluid circuit and a brake pad operably coupled to the hydraulic actuator such that the hydraulic actuator moves the brake pad, relative to the rotational component, between a disengaged position, in which the brake pad disengages the rotational component and allows rotation of the rotational component, and an engaged position, in which the brake pad engages the rotational component and prevents rotation of the rotational component, thus preventing rotation of the fan.

Abstract: A turbine engine includes a fan, a nacelle, and a thrust reverser system. The fan includes a plurality of fan blades. Each fan blade of the plurality of fan blades is rotatable about a pitch axis. The nacelle circumferentially surrounds the fan. The thrust reverser system includes a transcowl that forms a portion of the nacelle. The thrust reverser system translates the transcowl axially forward to an opened position during a reverse thrust condition and pitches the fan blades about the pitch axis to generate a reverse thrust through the turbine engine.
