    摘要: This invention concerns a system for cooling components in a gas turbine engine, the gas turbine engine comprising a compressor for driving a primary gas flow to a combustor and a turbine arranged to be driven by combustion gases from the combustor, wherein the system comprises: an annular cooling flow passage arranged for fluid communication between the compressor and the turbine, the flow passage having a first inlet arranged to receive gas from the primary gas flow downstream of compressor, and a second inlet located upstream of the first inlet, wherein the annular cooling flow passage has at least one internal wall for guiding airflow from the first inlet towards the airflow from the second inlet, such that the airflow from the first and second inlets coalesce within the annular flow passage prior to passing along the flow passage in a direction from the compressor to the turbine. The internal wall may guide the airflow from the first inlet in a rearward direction from the turbine to the compressor.

    摘要: A gas turbine engine (10, 41) for an aircraft. The gas turbine engine comprises a rotatable shaft (45) defining a rotational axis extending between rearward and forward ends of the gas turbine engine and a compressor drum (43) surrounding, and coupled to, the shaft so as to define an annular gap therebetween. An intermediate case (44) is arranged axially rearward of the compressor drum and comprising a bearing support element (46) extending into the annular gap. A rearward bearing (63) is mounted between the intermediate case and the shaft. A forward bearing (47) is forward of the rearward bearing, mounted between the bearing support element (46) and the shaft (45), and proximate a forward end of the compressor drum (43).

    摘要: A turbofan engine driveshaft comprises, in axial sequence along an axial centreline, a driving portion, and a driven portion. The driving portion has a first end and a second end. The second end of driving portion is connected to the driven portion. The driven portion comprises an annular drum having a radially inwardly facing surface, with the annular drum having a stiffener attached to the radially inwardly facing surface.
    The driveshaft is supported radially by a bearing assembly at the connection between the driving portion and the driven portion. The driving portion is configured to accommodate a predetermined range of movement of the outer end relative to the inner end.

    摘要: An aircraft cabin blower system is described having a hydraulic circuit comprising a first hydraulic device and a second hydraulic device. The first hydraulic device is mechanically coupled to a cabin blower compressor and the second hydraulic device is arranged in use to be mechanically coupled to a spool of a gas turbine engine. The first hydraulic device is capable of performing as a hydraulic motor and the second hydraulic device is capable of performing as a hydraulic pump. When, in use, the system is operating in a cabin blower configuration, a driving force supplied by the spool of the gas turbine causes the second hydraulic device to pump liquid provided in the hydraulic circuit and thereby to drive the first hydraulic device, which in turn rotates the cabin blower compressor.

    摘要: A system (200, 300, 360, 370, 400, 500) for supplying lubricant to a component (202) of a gas turbine engine (10) having a fan shaft (26) is provided. The system (200, 300, 360, 370, 400, 500) includes a pump (204) drivably couplable to the fan shaft (26) for pumping lubricant to the component (202). The pump (204) includes an inlet (206) for receiving lubricant from a lubricant source (208), an outlet (210) for outputting lubricant to the component (202) and a swashplate (220) movable between at least a first position (P1) and a second position (P2). The system (200, 300, 360, 370, 400, 500) also includes a swashplate actuator (222, 522) for actuating the swashplate (220) between the first position (P1) and the second position (P2) according to whether the fan shaft (26) is rotating in a forward direction (F) or a reverse direction (R) opposite to the forward direction (F).
