Abstract

The invention concerns a turboprop engine (2) in the pod (1) of which an airoil cooler (5) is disposed downstream of a cooling air inlet opening (7). The oil cooler exhaust air is discharged via an air duct (10) with which a cooling air conveying device (11) 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.
