Abstract
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.
Claims20
A turboprop engine, comprising:
- an engine casing defining an interior and defining an cooling air inlet opening into said interior for cooling air;
- a cooling air guiding duct adjoining said inlet opening, said cooling air guiding duct being directed to at least one assembly to be cooled;
- an air-liquid heat exchanger arranged in said interior;
- a cooling air delivery device arranged adjacent and upstream of said heat exchanger and downstream of said at least one assembly to be cooled;
- and
- an exhaust air guiding duct arranged adjacent and downstream of said heat exchanger.

A turboprop engine, comprising:
- an engine casing defining an interior;
- an assembly to be cooled arranged in said interior;
- a cooling air guiding duct communicating said interior with an ambient atmosphere, said cooling air guiding duct having an outlet arranged proximate said assembly to be cooled such that said cooling air guiding duct directs cooling air to said assembly to be cooled;
- an air-liquid heat exchanger arranged in said interior downstream of said assembly to be cooled;
- a cooling air delivery device arranged adjacent and upstream of said heat exchanger and downstream of said at least one assembly to be cooled;
- and
- an exhaust air guiding duct arranged adjacent and downstream of said heat exchanger.
