    摘要: The present invention provides an air management system with a set of compressed air sources for supplying pressurized air to air consumer equipment. In particular, either an air bleed system, electrical compressors, or a combination thereof may perform such supplying of compressed air depending on the aircraft operation condition.

    摘要: A gas turbine engine (20) includes a compressor section (24), a combustor (56), and a turbine section (28) having a high pressure turbine (54) comprising a plurality of turbine blades (130). The gas turbine engine (20) includes a tap (104) for tapping air that is compressed by the compressor section (24), to be passed through a heat exchanger (108) to cool the air, the cooled air to be passed to the plurality of turbine blades (130). A sensor (140) is located downstream of a leading edge of the combustor (56), and is configured to measure a characteristic of the cooled air. A controller (150) is configured to compare the measured characteristic to a threshold and control an operating condition of the gas turbine engine (20) based on the comparison.

    摘要: A valve assembly (100) comprising: a fluid flow passage (101) to permit the flow of a fluid through the valve assembly (100); a valve seat (102); and an actuator assembly (105). The actuator assembly comprises: a valve member (106) moveable relative to the valve seat (102) between a first position in which the valve member (106) is at least partially engaged with the valve seat (102) to at least partially block the fluid flow passage (101), and a second position in which the valve member (106) is remote from the valve seat (102); an actuator body (107) in a fixed position relative to the valve seat (102); and a metal bellows (108) that is attached to the valve member (106) and to the actuator body (107) and is disposed within the fluid flow passage (101). The valve member (106) of the actuator assembly is moveable relative to the actuator body (107) and extends around the actuator body (107) such that the actuator body (107) is disposed within the valve member (106).

    摘要: A controller assembly (100) comprises an electromechanical actuator (102) and a single-stage pneumatic flow switch (104) configured to thermally protect the electromechanical actuator (102) by a supply of cooling fluid. The single-stage pneumatic flow switch (104) is movable between a first mode in which the switch is configured to open a cooling fluid flow passage (106) and a second mode in which the switch is configured to close the cooling fluid flow passage (106). The electromechanical actuator (102) is coupled to a valve (110) movable between an open and a closed configuration.
