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.

The accessory system includes a towershaft coupled to the driveshaft and driven by the driveshaft along a towershaft axis of rotation. The accessory system also includes a shaft including a first shaft bevel gear coupled to a towershaft bevel gear. The shaft is rotatable by the towershaft along a shaft axis of rotation and defines an air-oil separator. The shaft axis of rotation is transverse to the towershaft axis of rotation. The accessory system includes a first accessory drive shaft having a first accessory bevel gear driven by the shaft. The accessory system also includes a second accessory drive shaft having a second accessory bevel gear driven by the shaft.

Abstract: A cooling system with a thin walled cooling plate. The system includes an enclosure with a cover that defines an interior space and that has an open side. Temperature sensitive devices are contained in the interior space. A cooling plate closes the open side and includes an inner side with a surface that is substantially flat and that faces into the interior. The cooling plate defines a flow channel adjacent the inner side that is configured to channel a circulating fluid to remove heat from the interior space. The flow channel extends across substantially all of the opening. An outer side of the cooling plate may be anodized to block heat from entering the interior space through the cooling plate.

Abstract: Gas turbine engines including multi-axis accessory gearboxes of mechanical drive systems are provided. The gearbox comprises a housing, a drive shaft, bevel pinion and drive shaft bevel gears, and a side bevel gear set operable to directly at least one side accessory device. Housing is disposed about a towershaft operatively coupled to main engine shaft and operable to rotate about a first axis. Drive shaft is skewed to main shaft and operable to rotate about a second axis that intersects the first axis at a first angle. Bevel pinion gear is mounted on the towershaft. Drive shaft bevel gear is mounted on the drive shaft. Side bevel gear set comprises an input gear meshing with one or more side bevel gears each having a side bevel gear axis at a second angle to the first axis and independently positionable relative to input gear. Second angle is independent of other angles.

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.
