摘要
A nozzle system (10) includes a multitude of circumferentially distributed divergent seals (21) that circumscribe an engine centerline (A). Each divergent seal (21) includes a multiple of divergent seal intakes (100) adjacent to a joint structure (42) to receive cooling airflow. Each divergent seal body is manufactured of a metallic hot sheet inner skin (102) and a metallic cold sheet outer skin (104). The skins (102, 104) form a multiple of longitudinal channels (106) which communicate with a multiple of edge channels (108) formed within the first longitudinal side (54) and the second longitudinal side (56) of each divergent seal. The multiple of edge channels (108) are located transverse to the longitudinal axis (L) and are raked aft to facilitate cooling of the gas path surface of each divergent seal (21) and adjacent divergent flaps (18).
