摘要： An oil accumulator assembly may comprise a scavenge tube including an aperture defined by a break in the scavenge tube and/or an annular cylindrical structure concentrically situated about the scavenge tube. The aperture may be configured to receive oil flowing through the scavenge tube, and the annular cylindrical structure may be configured to accumulate oil flowing through the aperture. The oil accumulator assembly may further comprise a drainage outlet disposed in the annular cylindrical structure. Oil accumulated within the annular cylindrical structure may drain through the drainage outlet in response to an engine being shut down. The oil accumulated within the annular cylindrical structure may fill a portion of the scavenge tube situated within an engine fan case to prevent coking within the scavenge tube.

摘要： A method and system for transitioning a gas turbine from burning gaseous fuel to liquid fuel and purging the liquid fuel therefrom after transfer back to the gaseous fuel are disclosed herein. The method includes pressurizing a volume of liquid fuel in an accumulator with a first volume of motive gas. A valve is opened in response to low gaseous fuel pressure in the gas turbine to permit the volume of liquid fuel to flow through a conduit to the gas turbine. A volume of flushing medium is pressurized in the accumulator with a second volume of motive gas. The valve is opened to permit at least a portion of the volume of flushing medium to flow through the conduit to flush any of the volume of liquid fuel remaining in the conduit after the gas turbine consumes the volume of liquid fuel.

摘要： A geared turbofan engine includes a fan rotatable about an engine axis. A compressor section compresses air and delivers the compressed air to a combustor where the compressed air is mixed with fuel and ignited to drive a turbine section that in turn drives the fan and the compressor section. A gear system is driven by the turbine section for driving the fan at a speed different than the turbine section. The gear system includes a carrier attached to a fan shaft. A plurality of planet gears are supported within the carrier. Each of the plurality of planet gears includes a first row of gear teeth and a second row of gear teeth supported within the carrier. A sun gear is driven by a turbine section. The sun gear is in driving engagement with the plurality of planet gears. At least two separate ring gears circumscribe the plurality of planet gears. Each of the at least two ring gears are supported by a respective flexible ring gear mount that enables movement relative to an engine static structure. A fan drive gear system for a gas turbine engine is also disclosed.

摘要： A gas turbine engine fuel system has an ecology valve for withdrawing residual fuel from primary and secondary fuel manifolds upon engine shut-down. The ecology valve has primary and secondary reservoirs respectively connected in fluid flow communication with the primary and secondary fuel manifolds. The valve further has a reciprocating piston movable from a retracted position when engine start-up is initiated to an extended position which the piston assumes under normal engine running conditions. The movement of the reciprocating piston between the retracted and extended positions controls the flow of fuel from and to the primary and secondary reservoirs. A cross-bleed passage is defined in the reciprocating piston. The cross-bleed passage connects the primary and secondary reservoirs in fluid flow communication only when the piston is in its extended position. In this way, the cross-bleed flow between the primary and secondary fuel manifolds may be initiated only at the end of the engine start-up phase.

摘要： A combustion staging system for fuel injectors of a multi-stage combustor of a gas turbine engine has pilot and mains fuel manifolds distributing fuel to the injectors. A splitting unit splits a fuel flow and sends portions of the flow to pilot and mains fuel manifolds to perform staging control of the combustor. The splitting unit can deselect the mains manifold so that there is no flow into the combustor from the mains manifold. A cooling flow recirculation line provides a cooling flow of fuel to the mains manifold when that manifold is deselected so that the mains manifold remains primed with relatively cool fuel. A return section collects the cooling flow from the mains manifold. One or more fuel pressure sensors detect pressure of the cooling flow on the recirculation line. A control arrangement closes off the recirculation line when the pressure sensor(s) indicates failure of the cooling flow.
