Abstract
A turbomachine engine according to aspects of the present disclosure is provided. The engine includes a fan assembly including a plurality of fan blades, and a core engine surrounded by an outer casing. The core engine includes a power output component operably connected to the fan assembly, a first input power source and a second input power source. The first input power source is counter-rotatable relative to the second input power source. The core engine includes a gear assembly operably connected to the power output component and configured to receive power from the first input power source and the second input power source.
Claims18
A turbomachine engine comprising:
- a fan assembly comprising a plurality of fan blades;
- and
- a core engine surrounded by an outer casing, wherein the core engine comprises:
- a power output component operably connected to the fan assembly, the power output component including a planet gear;
- a first input power source and a second input power source, wherein the first input power source is counter-rotatable relative to the second input power source;
- and
- a gear assembly operably connected to the power output component and configured to receive power from the first input power source and the second input power source, the gear assembly comprising a ring gear that rotates circumferentially about a gear assembly centerline axis, wherein the planet gear rotates circumferentially about the gear assembly centerline axis, and wherein one of the first input power source or the second input power source is coupled to the planet gear through the gear assembly, rotation of the one of the first input power source or the second input power source causes the ring gear to rotate, and the ring gear is coupled to the other one of the first input power source or the second input power source.
A gear assembly comprising:
- a power output component operably coupled to a fan assembly of a turbomachine engine, the power output component including a planet gear;
- a first input power source;
- and
- second input power source, wherein the first input power source is counter-rotatable relative to the second input power source,
- wherein the gear assembly is operably connected to the power output component and configured to receive power from the first input power source and the second input power source, the gear assembly comprising a ring gear that rotates circumferentially about a gear assembly centerline axis, wherein the planet gear rotates circumferentially about the gear assembly centerline axis, and wherein one of the first input power source or the second input power source is coupled to the planet gear through the gear assembly, rotation of the one of the first input power source or the second input power source causes the ring gear to rotate, and the ring gear is coupled to the other one of the first input power source or the second input power source.
