Abstract
A gas turbine engine augmentor includes an augmentor outer casing 502 and an annular augmentor liner 504 disposed radially within and radially separated from the augmentor outer casing 502 to form a generally annular augmentor liner cooling flow path 500 between the augmentor casing and the annular augmentor liner, and an augmentor flow splitter duct 506 disposed at the upstream end of the augmentor liner and radially between the augmentor outer casing 502 and the annular augmentor liner 504 and defining a splitter flow path 520 between the annular augmentor liner 504 and the annular augmentor flow splitter duct 506. 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 path 500 between an augmentor outer casing 502 and an annular augmentor liner 504, directing a portion of the air in the augmentor liner cooling flow path 500 into a splitter flow path 520 disposed radially outside the augmentor liner 504 and maintaining positive backflow pressure margin between air flow within the splitter flow path and the augmentor liner cooling flow path 500.
