Abstract: A fuel metering system for a combustion section of a turbo machine is provided. The turbo machine includes a main fuel line configured to provide a flow of fuel and a zone fuel line split from the main fuel line through which at least a portion of the flow of fuel is provided. A fuel valve is disposed at the zone fuel line and is configured to obtain and receive a present fuel valve area value and a present valve position value. A first pressure sensor is disposed upstream of the fuel valve, in which the first pressure sensor is configured to obtain a first pressure value. A second pressure sensor is disposed downstream of the fuel valve, in which the second pressure sensor is configured to obtain a second pressure value. A flow meter is disposed downstream of the fuel valve. A controller is configured to perform operations, in which the operations include determining a demanded fuel valve actuator position based at least on an estimated fuel valve actuator position and a demanded fuel flow; comparing the demanded fuel flow and a present fuel flow; determining an actual fuel valve actuator position based at least on the demanded fuel valve actuator position and the compared demanded fuel flow and present fuel flow; and generating an valve effective area at the fuel valve based at least on the actual fuel valve actuator position.

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 turbo engine for an aircraft includes a gas turbine engine having a fuel system to provide fuel to a combustion section. The fuel system includes a variable displacement pump driven by an accessory gearbox that is powered by a shaft of the gas turbine engine. The variable displacement pump has an inlet side and an outlet side. The variable displacement pump includes an actuator configured to adjust a discharge flow rate of the variable displacement pump. The fuel system also includes a fuel metering valve configured to receive pressurized fuel from the variable displacement pump and control a flow rate of the pressurized fuel to the combustion section. The fuel system further includes a bypass valve fluidly coupling the outlet side and the inlet side of the variable displacement pump to direct an excess portion of the pressurized fuel at the outlet side back to the inlet side.

Abstract: A method of delivering fuel to an engine during operation of the engine, that includes, sensing the speed of sound in the fuel, determining a density or property of the fuel, and based on that density or fuel property adjusting the flow rate of the fuel. Further, an established fuel profile or determined energy density value can also be used to adjust the flow rate of the fuel.

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: Methods and apparatus for measuring liquid fuel flows within a conduit are disclosed. An example flow sensor may include a conduit arranged to flow fuel therethrough along a flow axis, the conduit defining a flow area orthogonal to the flow axis. The flow sensor may further include a first transducer arranged to direct a first signal through the conduit proximate the flow area to a second transducer, the second transducer being arranged to direct a second signal through the conduit proximate the flow area to the first transducer, the first transducer being spaced apart from the second transducer by a signal path length, and in a direction parallel to the flow axis by an axial distance. The fuel flow measuring system may further include a processor arranged to calculate a fuel mass flow rate based on first and second signal transit times, known fuel properties and a fuel temperature.

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.
