Abstract
A method of assembling a gas turbine engine includes coupling at least one turbine nozzle segment within the gas turbine engine, each turbine nozzle segment includes at least one airfoil vane extending between an inner band and an outer band, wherein the airfoil vane includes a leading edge and a trailing edge, and wherein the outer band includes a front face, a rear face, and an inner surface extending therebetween. The method also includes coupling at least one turbine shroud segment downstream from the at least one turbine nozzle segment, wherein each turbine shroud segment includes a front face, a rear face, and an inner surface extending therebetween, and coupling a cooling fluid source to each turbine nozzle segment such that cooling fluid may be channeled to each turbine nozzle inner surface proximate to one of the leading edge and the trailing edge of each airfoil vane, such that cooling fluid channeled to each turbine nozzle outer band rear face is directed towards the front face of at least one turbine shroud segment.
