Abstract:
1. A method for fabricating a gas turbine engine augmentor system, said method comprising: fabricating an augmentor outer casing having at least one channel defined therein; fabricating a centerbody having at least one channel defined therein; fabricating a plurality of turbine frame vanes, wherein each turbine frame vane includes a first sidewall having a first channel defined therein, a second sidewall having a second channel defined therein, and at least one cross-fire tube extending between the first sidewall and the second sidewall; and coupling the plurality of turbine frame vanes to the augmentor outer casing and to the centerbody such that the first sidewall first channel formed on a first turbine frame vane, the second sidewall second channel formed on a second turbine frame vane, the augmentor channel, and the centerbody channel define a substantially contiguous trapped vortex chamber.
