Patent

CA 2660211

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.

La présente invention concerne le corps central du système d'échappement d'une turbine à gaz, dont extrémité amont se trouve à l'intérieur du carter de la tuyère d'échappement. Le corps central comprend plusieurs orifices de ventilation percés dans sa paroi et qui permettent une communication entre une cavité interne et le flux des gaz d'échappement entourant le corps central, de telle sorte que l'air de ventilation venant de la cavité puisse s'échapper dans ledit flux.
