An aircraft propulsion system comprises an engine 120 and a drive assembly 130 coupled to the engine. The drive assembly includes a first driveshaft 140 rotatable in a first direction about a first axis 142, a first fan 150 coupled to the first driveshaft to rotate in the first direction and a clutch assembly 160 to selectively disengage the first fan from the first driveshaft. The drive assembly may include a second driveshaft 180 rotatable in a second direction with a second fan 190 coupled to the second driveshaft to rotate in the second direction. The first and second driveshafts may be coaxial and the first and second fans will therefore be coaxial and contra-rotating. The drive assembly may include a gearbox 144 to enable the fans to be driven in different directions. The clutch may comprise a fluid coupling clutch.
