    Abstract: An accessory system for a gas turbine engine having a drive shaft with an axis of rotation is provided. Also provided is a bearing housing assembly for coupling the drive shaft of an accessory having a first gear to a gear associated with the accessory system. The bearing housing assembly includes a mount including an interface to be coupled to the accessory and defining a central bore, and a lock cylinder configured to receive the drive shaft. The lock cylinder is movable relative to the central bore and the drive shaft to adjust a contact pattern between the first gear of the drive shaft and the gear of the accessory system.

    Abstract: A mount system provides vibration isolation and support through a hybrid hard-soft configuration. The mount system includes a frame and a body connected with the frame. A first coupling element is provided on the body and defines a first opening. A second coupling element is provided on the frame and defines a second opening. A pin extends through the first and second openings to couple the body to the frame. At least one of the first and/or second openings operates as a damping hole with a series of slits disposed about the damping hole, so that the damping hole with the slits is configured to deflect to reduce the transmission of vibrations between the body and the frame.

    Abstract: An improved translating cowl (transcowl) assembly for a thrust reverser system for a turbine engine is provided. The transcowl assembly comprises an outer skin comprised of a first composite material and an inner skin comprised of a second composite material. The inner skin is configured to couple circumferentially within the outer skin and creates a flow path for engine exhaust flow. The inner skin comprises a contoured depression configured to provide clearance for movement of a blocker door. A metallic bracket is disposed between the inner skin and outer skin.

    Abstract: An accessory system for a gas turbine engine having a driveshaft with an axis of rotation is provided. The system includes a towershaft coupled to the driveshaft and rotatable about a towershaft axis of rotation. The towershaft includes a towershaft bevel gear. The system includes a primary shaft including a first bevel gear and a second bevel gear that each revolve about a primary shaft axis of rotation. The first bevel gear is coupled to the towershaft bevel gear. The system includes a secondary shaft including a third bevel gear and a fourth bevel gear that each revolve about a secondary shaft axis of rotation. The third bevel gear is coupled to the second bevel gear. The system includes a tertiary shaft including a fifth bevel gear that revolves about a tertiary shaft axis of rotation. The fifth bevel gear is coupled to the fourth bevel gear.

    Abstract: A fan structure having integrated rotor impeller, and methods of producing the same are provided. The fan structure includes a fan housing that encircles a longitudinal axis, and defines an airflow direction from an inlet side to an exit side. The integrated rotor impeller structure is disposed to rotate within the fan housing. The integrated rotor impeller structure includes (a) a cylindrical rotor shell being annular about the longitudinal axis, and having a shell length, and (b) an axis rod coaxial with the longitudinal axis, and having an axis rod length of less than or equal to the shell length. An airflow annulus is created therebetween. A blade is disposed within the airflow annulus to extend radially from the external surface of the axis rod to the inside surface of the the cylindrical rotor shell. One or more magnets are integrated within the integrated rotor impeller structure.

    Abstract: A thrust reverser system for a turbine engine includes a support structure, a transcowl, a door, and an anti-rotation structure. The transcowl is mounted on the support structure and has an inner surface. The transcowl is axially translatable, relative to the support structure, between first and second positions. The door is pivotally coupled to the turbine engine, and has a forward edge and an aft edge. The door is rotatable between stowed and deployed positions when the transcowl translates between the first and second positions, respectively. The anti-rotation structure extends from the transcowl and is disposed adjacent to the aft edge of the door when the transcowl is in the first position and the door is in the stowed position. The anti-rotation structure is configured such that door rotation out of the stowed position only occurs subsequent to or concurrently with translation of the transcowl out of the first position.
