D5/D5A DF-42 double walled exit cone and splash plate

A combustor basket assembly for a combustor in a gas turbine engine, said combustor basket assembly comprising:

• a combustor basket including a basket liner having an input end receiving air and fuel and an output end through which a hot working gas exits the combustor basket, said combustor basket further including a double-wall exit cone coupled to the basket liner at the output end, said double-wall exit cone including an inner cone wall and an outer cone wall defining an annular exit cone channel therebetween, each of the inner cone wall and the outer cone wall including an inner surface and an outer surface, where the outer surface of the inner cone wall and the inner surface of the outer cone wall face the annular exit cone channel, said combustor basket further including a splash plate mounted to the outer wall and extending parallel to the output end of the basket liner so as to define an annular splash plate channel therebetween, wherein the outer cone wall is attached to the combustor basket so as to allow a cooling air to be split between the double-wall exit cone and the splash plate;
• a plurality of pairs of adjacent cooling fluid feed holes provided in the basket liner and circumferentially disposed around the output end of the basket liner so that one of the feed holes in each of the plurality of pairs of adjacent cooling fluid feed holes is in fluid communication with the annular exit cone channel and is prevented from being in fluid communication with the annular splash plate channel and the other feed hole in each of the plurality of pairs of adjacent cooling fluid feed holes is in fluid communication with the annular splash plate channel and is prevented from being in fluid communication with the annular exit cone channel, and
• a spacer ring mounted to an outer surface of the output end of the basket liner and including a plurality of internal channels that provide the cooling air to the plurality of pairs of adjacent cooling fluid feed holes.
