Abstract
A gas turbine engine augmentor includes an augmentor outer casingand an annular augmentor linerdisposed radially within and radially separated from the augmentor outer casingto form a generally annular augmentor liner cooling flow pathbetween the augmentor casing and the annular augmentor liner, and an augmentor flow splitter ductdisposed at the upstream end of the augmentor liner and radially between the augmentor outer casingand the annular augmentor linerand defining a splitter flow pathbetween the annular augmentor linerand the annular augmentor flow splitter duct. A method of operating a gas turbofan engine including an augmentor includes directing a portion of fan bypass air into a generally annular augmentor liner cooling flow pathbetween an augmentor outer casingand an annular augmentor liner, directing a portion of the air in the augmentor liner cooling flow pathinto a splitter flow pathdisposed radially outside the augmentor linerand maintaining positive backflow pressure margin between air flow within the splitter flow path and the augmentor liner cooling flow path
