摘要： A gas turbine engine (10) includes a compressor section (12), a combustor section (14), and a turbine section (16) in fore-to-aft serial flow arrangement and defines an engine centerline (20). The combustor section (14) includes a combustor liner (40, 42) at least partially defining a combustor chamber (50), and a dome wall (70) coupled to the combustor liner (40, 42), and defining a forward end of the combustion chamber (50). A first fuel nozzle (72) is located on the dome wall (70) and fluidly coupled to the combustion chamber (50). A first set of compressed air openings (76a) emit compressed air into the combustion chamber (50) along a first flow path (F) and a second set of compressed air openings (76b) emit compressed air into the combustion chamber (50) along a second flow path (F). The first and second flow paths (F) intersect at an intersection point (94) to form a sheet of air (S).

摘要： A turbomachine engine (100, 210, 300, 410, 500) includes an engine core (123, 231, 344, 418) including a high-pressure compressor (112, 224, 318, 428, 518), a high-pressure turbine (116, 230, 432, 534), and a combustion chamber in flow communication with the high-pressure compressor (112, 224, 318, 428, 518) and the high-pressure turbine (116, 230, 432, 534). The engine core (123, 231, 344, 418) has a length (LCORE), and the high-pressure compressor (112, 224, 318, 428, 518) has an exit stage diameter (DCORE). A high-pressure shaft (122, 234, 548, 700) is coupled to the high-pressure compressor (112, 224, 318, 428, 518) and the high-pressure turbine (116, 230, 432, 534). The high-pressure shaft (122, 234, 548, 700) is characterized by a high-speed shaft (348, 436) rating (HSR) from 1.5 to 6.2, and a ratio of LCORE/DCORE is from 2.1 to 4.3.

摘要： A method for decoupling a mechanical drivetrain resonance mode of an inverter-based resource from the external electrical system includes receiving one or more voltage feedback signals at a node between the inverter-based resource and the external electrical system. The method also includes filtering the one or more voltage feedback signals to extract changes in a voltage at a frequency associated with the drivetrain resonance mode. Further, the method includes determining at least one current command or power command based on the filtered one or more voltage feedback signals. Moreover, the method includes controlling the power converter according to the at least one current command and controlling the energy buffer according to the power command so as to reduce or eliminate the changes in the voltage at the frequency associated with the drivetrain resonance mode.
