摘要： A method for detecting flameholding in at least one combustor of a turbine engine includes measuring dynamic pressure data of the at least one combustor of the turbine engine; converting the dynamic pressure data to frequency-domain spectral energy amplitudes for the dynamic pressure data; and comparing the spectral energy amplitudes against a dynamic amplitude threshold value to determine whether the amplitudes exceed the threshold minimum amplitude value, wherein exceeding the dynamic amplitude threshold indicates a flameholding occurrence.

摘要： An inline fluid damper device comprises a flow-through conduit configured to be placed inside a larger exterior conduit through which a fluid flows. The flow-through conduit is elongated and extending around a center axis. The damper device also comprising an indirect flow conduit coupled with the flow-through conduit. The indirect flow conduit is also configured to be placed inside the larger exterior conduit. The flow-through conduit and the indirect flow conduit are configured to dampen one or more flow fluctuations or pressure fluctuations in the fluid flowing in the larger exterior conduit by dividing the fluid into a first portion that flows along the center axis through the flow-through conduit and a second portion that concurrently flows outside of the flow-through conduit along the center axis and along a different direction.

摘要： Systems and methods for measuring temperature in a gas turbine are disclosed. The method can include directing a first acoustic signal and a second acoustic signal towards a gas path in a turbine; receiving the first acoustic signal and the second acoustic signal at a downstream gas path location; combining the first acoustic signal and the second acoustic signal to create a combined acoustic signal, wherein the combined acoustic signal forms at least one of either a signal maxima or a signal minima; and based at least in part on the combined acoustic signal, determining a temperature of the gas path.

摘要： The systems and methods described herein relate to a dome of a gas turbine assembly configured to suppress pressure pulsations. The systems and methods provide a dome having an aperture configured to surround an injector assembly of a combustor. The dome having a front panel extending radially from the aperture. The systems and methods couple a first cavity to the front panel. The first cavity includes a series of ducts. A first duct of the series of ducts is configured to receive airflow into the first cavity from a compressor and a second set of ducts of the series of ducts and a third duct of the series of ducts are configured to direct airflow to the combustor from the first cavity, wherein the third duct has a larger diameter than the second set of ducts.

摘要： The present disclosure is directed to a fuel manifold assembly for a gas turbine engine. The fuel manifold assembly defines a walled conduit through which a fuel flows in a fuel passage. The walled conduit defines a first end and a second end opposite of the first end along a length of the walled conduit. The fuel manifold assembly includes an exit manifold to which a fuel nozzle attaches. The fuel manifold assembly includes a damper assembly coupled to the walled conduit of the fuel manifold assembly. The damper assembly includes a walled tube extended from the walled conduit. The damper assembly further includes a walled enclosure defining a damper cavity therein. The damper cavity is in fluid communication with a damper passage defined within the walled tube, and the damper passage is in fluid communication with the fuel passage.
