Abstract: A reheat assembly for a gas turbine engine includes; a jetpipe casing defining a reheat core section configured to duct a core flow of air and a reheat bypass section configured to duct a bypass flow of air. The reheat bypass section is disposed radially outward of the reheat core section, and the reheat core section and the reheat bypass section are at least partially separated by a support duct. An integrated flameholder is mounted to the jetpipe casing, and a fuel pipe is configured to convey fuel to the integrated flameholder. The integrated flameholder includes a flameholder body extending radially inward from the jetpipe casing through the reheat bypass section and into the reheat core section to promote a wake-stabilised region downstream of the body; and an integrated atomiser configured to atomise fuel provided to the integrated flameholder and to discharge the atomised fuel into the wake stabilised region.

Abstract: A reheat assembly for gas turbine engine including a jetpipe casing having a reheat core section configured to flow air from inlet to outlet; and reheat bypass section configured to bypass air from inlet to outlet, wherein the reheat core section and the reheat bypass section are radially separated by support duct within the jetpipe casing; reheat arrangement including a radially extending flameholder and a core fuel injection port, wherein: the flameholder, mounted to the jetpipe casing, extends through the reheat bypass section and partly into the reheat core section; the flameholder is configured to form a wake-stabilised region within the core flow of air and the bypass flow of air downstream of the flameholder; and the core fuel injection port is: circumferentially aligned with the flameholder upstream of the wake-stabilised region, and configured to discharge fuel into the reheat core section for mixing with the core flow of air.
