COMBUSTOR ASSEMBLY FOR USE IN A TURBINE ENGINE AND METHODS OF ASSEMBLING SAME
First Claim
1. A combustor assembly for use with a turbine engine that includes a rotor assembly, said combustor assembly comprising:
- a casing comprising a plenum;
a combustor liner spaced a distance from said plenum and defining a combustion chamber therein;
a transition nozzle extending between said combustor liner and the rotor assembly for channeling combustion gases from said combustion chamber to the rotor assembly, said transition nozzle comprising a transition portion and a nozzle portion integrally formed with the transition portion; and
an annular flowsleeve coupled radially outward from said transition nozzle such that an annular flow path is defined between said flowsleeve and said transition nozzle, said flowsleeve comprising a plurality of openings extending through an outer surface of said flowsleeve for providing flow communication between said plenum and said annular flow path to facilitate impingement cooling of said flowsleeve.

Abstract
A combustor assembly for use with a turbine engine that includes a rotor assembly. The combustor assembly includes a casing that includes a plenum and a combustor liner that is spaced a distance from the plenum and that defines a combustion chamber therein. A transition nozzle extends between the combustor liner and the rotor assembly for channeling combustion gases from the combustion chamber to the rotor assembly. The transition nozzle includes a transition portion and a nozzle portion integrally formed with the transition portion. An annular flowsleeve is coupled radially outward from the transition nozzle such that an annular flow path is defined between the flowsleeve and the transition nozzle. The flowsleeve includes a plurality of openings extending through an outer surface of the flowsleeve for providing flow communication between the plenum and the annular flow path to facilitate impingement cooling of the flowsleeve.

17. A method of assembling a combustor assembly for use in a turbine engine, said method comprising:
-
coupling a combustor liner assembly to a casing such that the combustion liner is positioned within the casing and such that a combustion chamber is defined within the combustion liner; integrally forming a transition nozzle including a transition portion and a nozzle portion; coupling the transition nozzle to the combustor liner for channeling combustion gases from the combustion chamber to a rotor assembly; forming an annular flowsleeve including an inner surface that is oriented obliquely with respect to the rotor assembly; defining a plurality of openings through the flowsleeve inner surface to facilitate impingement cooling of the flowsleeve; and coupling the annular flowsleeve radially outwardly from the transition nozzle such that an annular flow path is defined between the flowsleeve and the transition nozzle. - View Dependent Claims (18, 19, 20)
