A turboprop engine in the pod of which an air-oil cooler is disposed downstream of a cooling air inlet opening. The oil cooler exhaust air is discharged via an air duct with which a cooling air conveying device is associated. In this way it is ensured that there is always a sufficient cooling air flow and that this air flow, as a relatively cold air flow, can also cool other units in the engine pod before acting on the oil cooler.
