Abstract: In accordance with one exemplary embodiment of the present disclosure, a method for providing overspeed protection for a gas turbine engine is provided. The gas turbine engine may include an engine core and an engine shaft. The method may include determining an overspeed condition of the engine. The overspeed condition may be indicative of an above normal rotational speed of the engine shaft. The method may also include reducing an airflow through the engine core of the gas turbine engine in response to the determined overspeed condition to reduce the rotational speed of the engine shaft.

Abstract: A pump mixer separator unit is provided in communication with a stripping gas line that provides an inlet stripping gas flow and a fuel line that provides an inlet fuel flow. The pump mixer separator unit includes a first pump in fluid communication with the stripping gas line and the fuel line to form a fuel/gas mixture flow and generate a first pressure rise from the inlet fuel flow to the fuel/gas mixture flow; and a second pump in fluid communication with the first pump, wherein the second pump receives the fuel/gas mixture flow from the first pump, wherein the second pump separates the fuel/gas mixture flow into an outlet stripping gas flow and an outlet fuel flow and generates a second pressure rise from the fuel/gas mixture flow to the outlet fuel flow, wherein the first pump includes a supplemental pump feature for drawing an inlet fuel flow through the fuel line during operation.

Abstract: A rotary actuator for control of variable geometry vanes is provided. The actuator is rotary so that operating components are internalized to protect fuel from contamination. The rotary actuator is a self-contained unit so that the device may be removed from the gas turbine engine without requiring removal of additional fuel system components. Finally, some embodiments of the rotary actuator may comprise multiple actuator loops to provide adjustment for two or more rows of vanes, independently.

Abstract: A direct metering architecture is provided having a metering pump and a servo pump wherein the metering and servo pumps are driven by an engine shaft by way of a gearbox transmission. The system reduces wasted horsepower previously occurring with oversized fixed displacement pumps, reduces instances of engine flameout and reduces the amount of heat added to fuel which ultimately improves engine oil cooling.

Abstract: Rotary vane actuator operated air valves associated with gas turbine engines are disclosed. An example gas turbine engine may include a fan, a compressor, a combustor, and a turbine in a serial flow relationship; a supply pipe arranged to convey compressed air from one or more of the fan and the compressor; a valve operatively disposed in the supply pipe, the valve including a rotatable valve member arranged to modulate flow of the compressed air through the supply pipe based upon an angular position of the valve member, the valve member being rotatable between an open position and a shut position; and/or a hydraulically operated rotary vane actuator operatively coupled to rotate the valve member.
