Abstract:
1. A gas turbine engine comprising an air flow passage and an oil cooler mounted to a wall of the air flow passage, the oil cooler including: a heat exchanger with an oil conduit for carrying a flow of heated oil proximal to the wall of the air flow passage, the heat exchanger being arranged to transfer heat from the heated oil to air flowing through the air flow passage, the heat exchanger being disposed entirely on a side of the wall of the air flow passage that contacts the air flowing through the passage; and a system for altering the flow of air across the heat exchanger, the system including an actuator for changing a position of the heat exchanger relative to the wall of the air flow passage, such that the heat transfer effectiveness of the heat exchanger can be adjusted.
