摘要： Dans un système de lubrification par barbotage, l'enceinte (17) de démarreur contenant le bain d'huile communique à travers un trou (22) percé dans la cloison de séparation (16) et muni d'une crépine de filtration (23) avec une enceinte intermédiaire (20) non polluante qui est alimentée en huile propre par le circuit de lubrification de la turbomachine. Un déversoir (24) déverse le trop-plein d'huile propre de ladite enceinte intermédiaire (20) dans le carter de boîtier de prise de mouvement (13) de la chaîne cinématique de la turbomachine.

摘要： An aircraft system is provided that includes a thrust rotor (22) and a powerplant (24) coupled to and configured to drive rotation of the thrust rotor (22). The powerplant (24) includes a gas turbine engine, a drivetrain (30) and a fluid motor (28). The gas turbine engine includes a rotating assembly (70), a compressor section (44), a combustor section (45), a turbine section (46) and a flowpath (42) extending through the compressor section (44), the combustor section (45) and the turbine section (46). The rotating assembly (70) includes a turbine rotor (58) in the turbine section (46). The turbine rotor (58) is configured to convert fluid power of combustion products flowing through the flowpath (42) within the turbine section (46) into mechanical power for driving rotation of the rotating assembly (70) during a mode of engine operation. The drivetrain (30) is configured to rotatably couple the fluid motor (28) to the rotating assembly (70). The fluid motor (28) is configured to boost the mechanical power for driving the rotation of the rotating assembly (70) during the mode of engine operation.

摘要： There is provided a method 200B of operating a gas turbine engine 101 having a spool 121, 122. The method comprises: executing 210B, by a controller 190, 190', a pre-shutdown procedure. The pre-shutdown procedure includes: determining 212B a parameter associated with a thermal condition of the gas turbine engine 101; and calculating 215B an idle period for an idle rotation operation to be performed 225B in a shutdown procedure. Calculation of the idle period is based on the determined parameter.

摘要： There is provided a blower system 400 for a gas turbine engine 10. The blower system 400 comprises: a rotor assembly 420, an airframe port 452 and a routing-control valve 46. The rotor assembly 420 is configured to be mechanically coupled to a spool 440 of the gas turbine engine 10. The airframe port 452 is configured to receive and discharge air to an airframe system 450. The routing-control valve 46 comprises: a primary channel 460 for bidirectional flow between the rotor assembly 420 and the airframe port 452; a primary valve member 480 configured to open and close the primary channel 460; and an auxiliary channel 461 branched from the primary channel 460. The auxiliary channel 461, 462 is configured to bypass the primary valve member 480 for: a first auxiliary flow from the airframe port 452 to the rotor assembly 420; or a second auxiliary flow for purging air from the rotor assembly 420 to a discharge port 422. The blower system 400 is configured to operate in an engine drive mode in which air received from the airframe port 452 drives a rotor 410 of the rotor assembly 420 to rotate the spool 440, and in a blower mode in which the spool 440 drives the rotor 410 to discharge air to the airframe port 452.
