Abstract: An oil supply system for a gas turbine engine has a lubricant pump delivering lubricant to an outlet line. The outlet line is split into at least a hot line and into a cool line, with the hot line directed primarily to locations associated with an engine that are not intended to receive cooler lubricant, and the cool line directed through one or more heat exchangers at which lubricant is cooled. The cool line then is routed to a fan drive gear system of an associated gas turbine engine. A method and apparatus are disclosed. The heat exchangers include at least an air/oil cooler wherein air is pulled across the air/oil cooler to cool oil. The air/oil cooler is provided with an ejector tapping compressed air from a compressor section to increase airflow across the air/oil cooler.

Abstract: A gas turbine engine has a spool, a towershaft connected to the spool and an impeller pump. An integrated drive pump is connected to the towershaft and to the impeller pump for driving the impeller pump at a constant speed. The integrated drive pump is positioned on an engine core. The gas turbine engine includes a fan and a bypass duct located between a cowl and the engine core. The gas turbine engine includes an intake manifold for the impeller pump, and the intake manifold receives air from the bypass duct.

Abstract: An engine comprises a fan configured to produce propulsive thrust from a fan discharge air stream. A bypass duct is located between a cowl and an engine core, the bypass duct is fluidly coupled to the fan. The bypass duct contains the air stream created by the fan. A pump system provides the air to an environmental control system. The pump system comprises an impeller having an inlet for receiving the air from the duct and an outlet for discharging the air to the environmental control system. An intake manifold is configured to receive the air from the bypass duct and to deliver the air to the inlet. A single discharge manifold is configured to deliver the air from the outlet to the environmental control system.

Abstract: A gas turbine engine includes a buffer system that can communicate buffer supply air to a portion of the gas turbine engine. The buffer system can include a first circuit and a second circuit. The first circuit selects between a first bleed air supply having a first pressure and a second bleed air supply having a second pressure that is greater than the first pressure to render a first buffer supply air having an intermediate pressure. The second circuit selects between a third bleed air supply and a fourth bleed air supply to communicate a second buffer supply air.
