Abstract
A combustor basket assembly for a gas turbine engine that includes a combustor basket having a basket liner including an input end and an output end. An integrated exit cone and splash plate member is affixed to the output end of the basket liner and includes a base portion, an exit cone portion and a splash plate portion. The base portion includes an annular cooling channel that receives a cooling air flow and the exit cone portion and the splash plate portion each include an array of cooling feed holes in fluid communication with the cooling channel. The spacing between the feed holes and the size of the feed holes can be optimized to provide more cooling for hotter regions.
Claims20
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 and an output end through which a hot working gas exits the combustor basket, said combustor basket further including a single piece exit cone and splash plate member affixed to the output end of the basket liner, said exit cone and splash plate member including a base portion, a splash plate portion integral with the base portion and an exit cone portion integral with the base portion, where the hot working gas exits the combustor basket through the exit cone portion.
An annular single piece exit cone and splash plate member operable to be affixed to an output end of a basket liner associated with a combustor in a gas turbine engine, said exit cone and splash plate member comprising a base portion, a splash plate portion integral with the base portion and an exit cone portion integral with the base portion.
A gas turbine engine comprising:
- a shaft provided along a center line of the turbine;
- a compressor section responsive to a working fluid and being operable to compress the working fluid to produce a compressed working fluid;
- a combustion section in fluid communication with the compressor section that receives the compressed working fluid, said combustion section including a plurality of combustors that mix the compressed working fluid with a fuel and combust the compressed fluid and fuel mixture to produce a hot working gas, each combustor including a combustor basket assembly in which the combustion occurs, said combustor basket assembly comprising a combustor basket including a basket liner having an input end and an output end through which the hot working gas exits the combustor basket, said combustor basket further including a single piece exit cone and splash plate member affixed to the output end of the basket liner, said exit cone and splash plate member including a base portion, a splash plate portion integral with the base portion and an exit cone portion integral with the base portion, where the hot working gas exits the combustor basket through the exit cone portion;
- and
- a turbine section in fluid communication with the combustion section, said turbine section expanding the hot working fluid to produce mechanical power through rotation of the shaft.
