ABSTRACT:
Problems with the cooling of a turbine nozzle (60) and a turbine wheel (20) of a gas turbine engine when the engine is uprated may be avoided or minimized by employing a combustor (36) that is free of any means for providing cooling air films on the interior walls thereof and which allows the entry of only stoichiometric quantities of air into the interior of the combustor (36) at predetermined locations along the entire axial length thereof. Consequently, the entirety of the combustor (36) is available for combustion. Cooling of the nozzle (60) and components of the engine downstream thereof is handled by the provision of an annular opening (96) immediately upstream of the leading edges (98) of the vanes (58) constituting the nozzle (60) along with apertures (102) in a front turbine shroud (30) and aligned with leading edges (98). Air from the engine compressor (18) is flowed through the apertures (102) and the opening (96).
