摘要： An air turbine starter (10, 210, 410, 610, 810) includes a housing (30) having a primary inlet (32) and primary outlet (34) to define a primary air flow path (36) from the primary inlet (32) to the primary outlet (34). A turbine (54) that includes a rotor (58) with a plurality of circumferentially spaced blades (60) extends into the primary air flow path (36) and is operably coupled with a drive shaft (66). A gear box (72) that includes a gear train (68) couples to the drive shaft (66). A first bearing assembly (74) is located between the drive shaft (66) and the housing (30). A second bearing assembly (114, 116) rotatably supports a carrier (82, 282, 482, 682) coupled to the gear train. A third bearing assembly (102, 302) is located between the carrier (82, 282, 482, 682) and the housing (30).

摘要： There is provided a blower system 400 for providing air to an airframe system 450, comprising a rotor 410 configured to be mechanically coupled to a spool 440 of a gas turbine engine 10, wherein the rotor 410 is configured to: in a blower mode, be driven to rotate by the spool 440 to discharge air to an airframe discharge port 426 for supply to an airframe system 450; and, in an engine drive mode, receive air from an external air source 470 via an impingement port 424 that is configured to direct the received air onto the rotor and thereby drive the rotor to rotate to drive the spool 440 to.

摘要： There is provided a blower assembly 400 for providing air to an airframe system, comprising a rotor 410 configured to be mechanically coupled to a spool 440 of a gas turbine engine 10 and a flow modifier 510, 520 configured to receive and/or direct flow to the rotor 410; wherein the blower assembly 400 is configured to permit relative movement between the rotor 410 and the flow modifier 510, 520 to move between: a compressor configuration in which the rotor 410 is configured to be driven to rotate by the spool 440 and to receive and compress air from the gas turbine engine 10, and discharge the compressed air for supply to the airframe system; and a turbine configuration in which the rotor 410 is configured to receive air from an external air source 470 to drive the spool 440 to rotate.
