ABSTRACT:
A method of, and apparatus, for, controlling the temperature of pressurized air such as bleed air from a gas turbine engine, wherein the air is passed through a heat exchanger to exchange heat with coolant air which is caused to flow through the heat exchanger by operation of an ejector device powered by some of the pressurized air, the supply of the pressurized air to the ejector device is controlled to control the flow of coolant air and hence control the temperature of the pressurized air downstream of the heat exchanger.
