SELECTIVE POWER DISTRIBUTION FOR AN AIRCRAFT PROPULSION SYSTEM - A simplified explanation of the abstract

This abstract first appeared for US patent application 18202736 titled 'SELECTIVE POWER DISTRIBUTION FOR AN AIRCRAFT PROPULSION SYSTEM

Simplified Explanation

The patent application describes an assembly for an aircraft that includes a rotating structure, a geartrain, a propulsor rotor, and an electric machine.

  • The rotating structure consists of a turbine rotor.
  • The geartrain is composed of a sun gear, a ring gear, multiple intermediate gears, and a carrier.
  • The sun gear is driven by the rotating structure and is capable of rotation.
  • Each intermediate gear is positioned between the sun gear and the ring gear and is meshed with both gears.
  • The intermediate gears are mounted on the carrier and can rotate.
  • The propulsor rotor is driven by the carrier and is capable of rotation.
  • The electric machine is connected to the ring gear.


Original Abstract Submitted

An assembly is provided for an aircraft. The aircraft assembly includes a rotating structure, a geartrain, a propulsor rotor and an electric machine. The rotating structure includes a turbine rotor. The geartrain includes a sun gear, a ring gear, a plurality of intermediate gears and a carrier. The sun gear is rotatably driven by the rotating structure. Each of the intermediate gears is between and meshed with the sun gear and the ring gear. Each of the intermediate gears is rotatably mounted to the carrier. The propulsor rotor is rotatably driven by the carrier. The electric machine is coupled to the ring gear.
