Abstract
A centerbody for the exhaust system of a gas turbine engine having an upstream end mounted within an exhaust duct casing of the exhaust system. The centerbody includes a plurality of ventilation openings defined in a centerbody wall which provide fluid flow communication between an internal cavity and exhaust gas flow surrounding the centerbody, such that ventilating air from within the cavity can exit into the exhaust gas flow.
