    摘要： An air-blast fuel nozzle assembly includes a housing having an inner surface defining an interior chamber around a central axis. The inner surface terminates in an exit aperture. An air swirler pneumatically communicates with the interior chamber and has vanes operative to impart a swirling motion to air passing across the vanes and into the interior chamber. A fuel injection assembly includes a nozzle portion extending along the central axis and having a plurality of outlets circumferentially-arranged around the central axis that are directed into the interior chamber toward the inner surface of the housing. A shield extends radially outwardly from the nozzle portion upstream of the plurality of outlets. The shield extends between a base at the nozzle section and a free tip end such that the shield extends partially across the interior chamber toward the inner surface.

    摘要： Systems and methods reducing thermo-acoustic coupling of a gas turbine engine augmentors are provided. In this regard, a representative method includes: determining acoustic resonances and heat release phase relationships associated with the augmentor; and determining relative axial positions of a fuel injector and a flame holder of the augmentor that result in reduced thermo-acoustic coupling of the augmentor during operation.

    摘要： A system and method periodically sample a fluid stream in a conduit for undergoing analysis thereof. A sampling tube having a probe is joined to the conduit for removing samples from the stream flowing therethrough. An analyzer is joined to the sampling tube for analyzing the removed samples. A solenoid valve is disposed in the tube for controlling flow of the samples to the analyzer. A dynamic pressure transducer is joined to the conduit so that a specific dynamic pressure reference frequency of the stream in the conduit may be locked-on to and used for periodically switching the solenoid valve open and closed for intermittently removing stream samples from the conduit at the reference frequency for channeling to the analyzer periodic stream samples at a sampling frequency corresponding to the reference frequency. In a preferred embodiment, the solenoid valve is switched open at a specific sampling phase in the sampling frequency, which phase may be indexed for obtaining different periodic samples at the sampling frequency for measuring periodic and short duration concentration fluctuations.

    摘要： A turbine engine augmentor has a centerbody within a gas flowpath. A flameholder is positioned in the flowpath outboard of the centerbody. A burner within the centerbody has an outlet for expelling combustion products of a first pilot fuel. A pilot fuel conduit has an outlet positioned to introduce a supplemental pilot fuel to the expelled combustion products.
