Abstract: A turbine engine having a longitudinal centerline axis. The turbine engine including a fan comprising a plurality of fan blades that rotate about the longitudinal centerline axis and a rotational component coupled to the fan. The turbine engine including a fluid circuit for supplying fuel or lubricant to the turbine engine and a hydraulic fan brake coupled to the fluid circuit to prevent rotation of the rotational component, thus preventing rotation of the fan. The hydraulic fan brake including a hydraulic cylinder fluidly coupled to the fluid circuit and a valve coupled to the hydraulic cylinder and having a first valve position that disengages the hydraulic fan brake to allow rotation of the rotational component and a second valve position that engages the hydraulic fan brake to prevent rotation of the rotational component.

Abstract: A cover for a universal joint of a driveshaft comprises a first section, a second section, at least two cover fasteners, and at least one driveshaft fastener. At least a first cover fastener of the at least two cover fasteners is configured to connect a first section first edge to a second section first edge. At least a second cover fastener of the at least two cover fasteners is configured to connect a first section second edge to a second section second edge. The at least one driveshaft fastener is configured to connect the cover to the driveshaft or a yoke thereof without any portion of the cover contacting the universal joint.

Abstract: Kits for a cover for a universal joint of a driveshaft include at least a first section and a second section of a cover, at least two cover fasteners, and at least one driveshaft fastener. The at least two cover fasteners configured to connect the first section to the second section, and the at least one driveshaft fastener configured to connect the cover to the driveshaft or to a yoke of the driveshaft without any portion of the cover contacting the universal joint. The kits also include a plurality of inserts and/or a plurality of pads configured to allow the cover to adapt to driveshafts of varying diameters without changing the size or shape of the cover itself.
