An aircraft propulsion system (10) comprises first and second propulsors (13a, 13b). An epicyclic reduction gearbox (25) is coupled to an input shaft (24). The reduction gearbox (25) comprises a sun gear (27) coupled to the input shaft (24), a plurality of planet gears (28) which mesh with the sun gear (27) and are mounted to a planet carrier (30), and a ring gear (29) which meshes with the plurality of planet gears (28). The first propulsor (13a) is located upstream of the second propulsor (13b). The first propulsor (13a) is coupled to the sun gear (27), and the second propulsor (13b) is coupled to one of the planet carrier (30) and the ring gear (29).
