ABSTRACT:
A gas turbine engine nozzle includes outer and inner bands and a plurality of spaced apart vanes extending therebetween. The inner band includes an outer surface facing the outer band over which is flowable combustion gases, and a radially inwardly facing inner surface. A plurality of circumferentially spaced apart turbulators are joined to the inner band inner surface adjacent the trailing edges of the vanes for increasing cooling of the inner band by cooling air channeled over the turbulators.
