    摘要: The invention provides a bleed air system (1) of an engine and a method for controlling the temperature of a bleed air flow in said bleed air system. The method comprising the steps of: sensing a duct temperature in the bleed air duct (2) downstream the pre-cooler (4), sensing an ejector pressure in an ejector valve, measuring the flap position, establishing a target value in terms of temperature variation, setting the operation of the bleed air system in either a first mode where the control means actuate on the actuator, or in a second mode, where the control means actuate on the ejector valve, calculating a new target value, which in the event the bleed air system is operating in the first mode, the new target value is a target flap position and in the event the bleed air system is operating in the first mode, the new target value is a target ejector pressure, and actuating either on the actuator or on the ejector valve so that the flap or the ejectors acquires the new target value.

    摘要: A method for recovering air in an aircraft includes bleeding bypass air (122;196) from an engine bypass (76;152), bleeding core air (120;194) from an engine core (74;150), and placing the bypass air and the core air in a heat exchange relationship to produce heated bypass air (126;200) and cooled core air (124;198). The method further includes directing the heated bypass air to one or more of: the engine bypass (76), a cowl (149) de-icing system, and a wing (206) anti-ice system.

    摘要: A gas turbine engine (12) comprises a main compressor section having a high pressure compressor (141) with a downstream most end, and more upstream locations. A turbine section has a high pressure turbine (144). A first tap taps (126) air from at least one of the more upstream locations in the main compressor section, passing the tapped air through a first heat exchanger (122) and then to a cooling compressor (124). A second tap (140) taps air from a location closer to the downstream most end than the location of the first tap, and the first and second taps mix together and are delivered into the high pressure turbine (144). The cooling compressor (124) is positioned downstream of the first heat exchanger (122), and upstream of a location where air from the first and second taps mix together.
