摘要： A variable geometry inlet guide vane assembly that reduces stress placed on downstream compressor blades in gas turbine engines is disclosed. The invention circumferential leans upstream guide vanes (303), pushing engine core air flow radially. This allows for aerodynamic stresses on the downstream blades to be reduced. The invention overcomes the difference in movement between a unison ring (319) and a vane arm (405) by providing a hinge (505) in conjunction with a spherical bearing (503) that couples to the unison ring (319).

摘要： A gas turbine engine (10) includes a spool, a gearbox (54) having gearing driven by the spool, and a lubrication system (12). The lubrication system includes a first heat exchanger (32) positioned in a first air flow path (40), a second heat exchanger (34) positioned in a second air flow path (42), and a lubrication pump (48) fluidically connected to both the first heat exchanger and the second heat exchanger. A first air fan (36) is driven by the gearbox for inducing air flow through the first air flow path. A second air fan (38) is driven by an electric motor for inducing air flow through the second air flow path.

摘要： A buffer air pump (35) provides pressurized cooling air for cooling components of a gas turbine engine. The buffer air pump (35) is supported on and/or within an accessory gearbox (30) and draws bypass air in through an inlet manifold (32). An impeller (52) supported within a scroll housing (34) pressurizes the incoming bypass air and directs the pressurized air through passages to a component requiring cooling. The buffer air pump (35) draws in relatively cool air from the bypass flow, pressurizes the air with the impeller (52) and sends the air through conduits and passages (56) within the gas turbine engine to the component that requires cooling such as a bearing assembly.
