Abstract (en)
[origin: EP2264282A2] A stator assembly (100) for a gas turbine engine is provided having an annular body (10), an inner gas path platform (30), a plurality of fairings (20), and at least one nozzle (50). The annular body (10) has an outer gas path platform (12) and a circumferentially extending annular cavity (14) disposed radially outside of the outer gas path platform (12). The fairings (20) extend radially between the inner gas path platform (30) and the outer gas path platform (12). Each fairing (20) includes a gas passage (22) extending from the annular cavity (14) through the inner gas path platform (30). The at least one nozzle (50) has an inlet orifice (52) disposed outside of the annular cavity (14) and an exit orifice (54) disposed within the annular cavity (14). The exit orifice (54) is oriented within the annular cavity (14) such that cooling air exiting the nozzle (50) travels in a substantially circumferential direction within the annular cavity (14).
