    Abstract: A turbine engine for an aircraft includes a turbo-engine with a core air flow path, a fan having a fan shaft coupled to the turbo-engine to rotate the fan shaft, and a steam system. The core air flow path includes a plurality of core air flow path zones. A combustor is positioned in the core air flow path to combust fuel and to generate combustion gases. The steam system extracts water from combustion gases and vaporizes the water to generate steam. The steam system is fluidly coupled to a core air flow path to inject the steam into the core air flow path at a plurality of steam injection zones to add mass flow to the core air. Each steam injection zone of the plurality of steam injection zones corresponds to a core air flow path zone of the plurality of core air flow path zones.

    Abstract: A method for controlling the operation of a gas turbine includes monitoring an operating parameter of the gas turbine engine. The method also includes determining a first position demand for controlling an operation of a first actuator based on the monitored operating parameter. In addition, the method includes controlling the operation of the first actuator based on the first position demand to adjust the angular position of at least one airfoil included within a first array of airfoils. The method further includes determining a second position demand for controlling the operation of a second actuator based on the first position demand. In addition, the method also includes controlling the operation of the second actuator based on the second position demand to adjust the angular position of at least one airfoil included within a second array of airfoils.

    Abstract: Systems and methods of aircraft thrust management are provided. For example, a propulsion system for an aircraft comprises a fuel cell assembly comprising a fuel cell, a turbomachine, and a controller comprising memory and one or more processors. The memory stores instructions that, when executed by the one or more processors, cause the propulsion system to perform operations including receiving data indicative of a propulsion system thrust discrepancy and modifying an output of the fuel cell in response to receiving data indicative of the propulsion system thrust discrepancy. Modifying the fuel cell output may include modifying output products, an electrical power output, or both of the fuel cell to balance the thrust provided by the propulsion system.

    Abstract: A turbine engine for an aircraft includes a turbo-engine with a core air flow path, a fan having a fan shaft coupled to the turbo-engine to rotate the fan shaft, and a steam system. A combustor is positioned in the core air flow path to combust fuel and to generate combustion gases. The steam system is fluidly coupled to the core air flow path to provide steam to the core air flow path. The steam system includes a boiler to generate the steam, a water pump, and a controller. The water pump is in fluid communication with the boiler to direct a flow of water into the boiler. The controller is operatively coupled to the water pump to control the output of the water pump, the flow of the water into the boiler, and the amount of the steam injected into the core air flow path.

    Abstract: A turbine engine for an aircraft. The turbine engine includes a combustor, a core shaft, a turbine, and a steam system providing steam to a core air flow path. The steam system includes a boiler that receives combustion gases to boil water to generate steam. A steam turbine is fluidly coupled to the boiler to receive the steam from the boiler and to cause the steam turbine to rotate. The steam turbine is coupled to the core shaft to rotate the core shaft when the steam turbine rotates. The steam system may include a bypass flow path selectively operable to redirect at least one of the steam or water, and to bypass the core air flow path. The turbine engine may also include at least one steam control valve located downstream of the boiler and upstream of the core air flow path to control the flow of steam.
