Aircraft propulsion system geartrain

An assembly for an aircraft, comprising:

• a geartrain comprising a sun gear, a ring gear, a plurality of intermediate gears and a carrier, the sun gear rotatable about an axis, the ring gear circumscribing the sun gear and rotatable about the axis, each of the plurality of intermediate gears between and meshed with the sun gear and the ring gear, and each of the plurality of intermediate gears rotatably mounted to the carrier;
• a propulsor rotor coupled to the sun gear;
• and
• a rotating structure coupled to the ring gear, the rotating structure comprising a turbine rotor, and the rotating structure configured to drive rotation of the propulsor rotor through the geartrain.
