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.

Integral combustor splash plate and sleeve

A double annular combustor having concentrically disposed inner and outer annular combustors is provided with inner and outer domes. A one-piece cowl is provided upstream of the inner and outer domes in order to form a high pressure region. The one-piece cowl has an inner annular portion, an outer annular portion, and a radial middle portion connecting the inner and outer annular portions. The inner and outer annular portions include scalloped areas therein to facilitate insertion and removal of fuel tubes and nozzles. The cowl middle portion includes a shield to isolate the scalloped areas and the fuel tube from the high pressure region, thereby preventing leakage of air flow and consequential pressure loss from the high pressure region.

One-piece cowl for a double annular combustor

A double annular combustor having concentrically disposed inner and outer annular combustors is provided with inner and outer dome plates. Each dome plate has an inner portion and an outer portion. A cowl structure having an inner portion, an outer portion and a middle portion is also provided. The cowl outer portion is connected to the outer dome plate outer portion, the cowl inner portion is connected to the inner dome plate inner portion, and the cowl middle portion is connected to the outer dome plate inner portion and the inner dome plate outer portion. at an outer end, an inner end, and a middle portion. Additionally, the inner and outer annular combustors may lie in distinct radial planes, whereby the dome plate of the downstream annular combustor includes a section extending upstream to the cowl middle portion.
