Abstract: An interconnect drive system for an aircraft (11) has a driveline (43) and clutch control system. The driveline (43) comprises a shaft (45, 47, 49) for each propulsion assembly, each shaft for transferring torque to and from the associated propulsion assembly (25, 27), and a clutch (53) operably coupling the shafts and configured for selective engagement. The clutch is capable of transferring a first amount of torque between the shafts while engaged and a second amount of torque between the shafts while disengaged. The system also has a clutch control system (57), comprising a computer (59) operably connected to the clutch (53) for controlling operation of the clutch and sensors (61) for sensing torque applied to the driveline (43), output from the sensors being communicated to the computer. The computer commands operation of the clutch in response to the output from the sensors, the clutch being commanded to disengage to relieve a transient torque imbalance in the driveline.
