    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 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 control system may generate a first simulated value for an aircraft sensor by applying one or more first input parameters to a sensor map model via a processor. The control system may compare the first simulated value and the first output of the aircraft sensor to determine a first calibration value and save calibration data in a memory based on the first calibration value. The control system may generate a calibrated simulation value of the aircraft sensor based on the sensor map model and the calibration data. The control system may determine validity of a second output of the aircraft sensor, utilize the second output of the aircraft sensor to perform an operation of the aircraft when the second output of the aircraft sensor is valid, and utilize the calibrated simulation value to perform the operation of the aircraft when the second output of the aircraft sensor is invalid.

    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.
