A drive unit (40) for an aircraft ground wheel (? 2) associated with a brake unit (30) for braking the ground wheel (12) is disclosed, the drive unit (40) comprising a driving motor (42) being drivingly coupleable to the ground wheel (12); and a cooling system including at least a drive cooling unit (52) being configured to generate a drive cooling air stream (54) for cooling the drive unit (40) and a brake cooling unit (62, 70; 72, 74) configured to generate a brake cooling air stream (64) by sucking in air from the brake unit (30). Further disclosed is a method of controlling such drive unit (40) in which the cooling system is driven by the driving motor (42) of the drive unit (40), the method comprising decoupling the driving motor (42) from the ground wheel (12) and increasing the rotational speed of the driving motor (42) to increase the amount of generated drive cooling air (54), when an operating condition of the ground wheel (12) and/or of the drive unit (40) is switched from a propulsion mode to a non-propulsion mode. |
