Abstract: A ventilation system includes a cavity, a fluid motive force device, and a motive fluid supply system. The cavity includes different ventilation level requirements for a plurality of modes of operation. The fluid motive force device includes a suction port, an outlet port, and a motive fluid inlet port. The suction port is coupled in flow communication with the cavity to be vented. A flow supply to the motive fluid inlet port determines a ventilation flow through the suction port. The motive fluid supply system is coupled in flow communication with the motive fluid inlet port. An operation of the motive fluid supply system determines a flow of motive fluid from the motive fluid supply system to the motive fluid inlet port. The flow of motive fluid to the motive fluid inlet port generates a ventilation flow through the suction port approximately matching a current ventilation demand of said cavity.

Abstract: A system for lubricating components of a gas turbine engine includes a supply pump to pump lubricant from a reservoir through a supply conduit to lubricated component. An outer body deicing circuit is fluidly coupled in series with the supply conduit. Moreover, a scavenge conduit extends from the lubricated component to the reservoir and a scavenge pump pumps the lubricant from the lubricated component through the scavenge conduit. In addition, a valve is fluidly coupled in series with the supply conduit and the scavenge conduit and a bypass conduit extends from the valve to a location on the supply conduit downstream of the deicing circuit. When the lubricant is supplied to the valve, the valve directs the lubricant flowing through the scavenge conduit into the reservoir. When the supply of lubricant to the valve is halted, the valve directs the lubricant flowing through the scavenge conduit into the bypass conduit.

Abstract: A flow vortex spoiler including an oil sump wherein pressurization air flow moves about the oil sump through a sump pressurization cavity, the cavity having an inlet, a circumferential plate disposed across a portion of the pressurization cavity near the inlet. The circumferential plate is disposed at said inlet to said sump pressurization cavity. The circumferential plate has a plurality of closely spaced apertures. The pressurization air has a radial component and a tangential component wherein the circumferential plate and the plurality of closely spaced apertures substantially reduce the tangential component of the pressurization air and further wherein the vortex spoiler inhibits excessive pressure change within the pressurization cavity and inhibits oil leakage at seals adjacent to the oil sump.
