A first gear system (94) includes a first sun gear (98), a first ring gear (100), first intermediate gears (102) and a first carrier (104). The first intermediate gears (102) are between and meshed with the first sun gear (98) and the first ring gear (100). Each first intermediate gear (102) is rotatably mounted to the first carrier (104). A second gear system (96) includes a second sun gear (108), a second ring gear (110), second intermediate gears (112) and a second carrier (114). The second ring gear (110) is coupled to the first carrier (104). The second intermediate gears (112) are between and meshed with the second sun gear (108) and the second ring gear (110). Each second intermediate gear (112) is rotatably mounted to the second carrier (114). A first propulsor rotor (22) is coupled to the first carrier (104). A rotating structure (68) is coupled to the first ring gear (100) and includes a turbine rotor (60). The rotating structure (68) is configured to drive rotation of the first propulsor rotor (22) through the geartrain (72).
