A centerbody is disposed between the inner and outer domes and is constructed of a plurality of annular segments. Each segment includes an upper wall, a lower wall, an upstream wall and a downstream end. The upper and lower walls include flanges extending therefrom to form cavities, within which are cooling holes. Pins are also provided which extend between the upper and lower walls of the centerbody to augment the cooling and structural connection thereof.

A carburetor for the combustor of a gas turbine engine wherein a swirler and a venturi cooperate to atomize and mix air and fuel for the combustor, wherein a downstream mounted integrally formed sleeve and splash plate is provided to control the flow of the air/fuel mixture into the combustor. The integral splash plate and sleeve has protuberances formed on its upstream surface to increase the area impinged by cooling air and thereby enhance cooling of the splash plate flange thereof.
