摘要： A gas turbine engine component has an annular flange arm (61), a backing plate mounted to the flange arm (61) and a bypass circuit (72) formed between the flange arm (61) and the backing plate. The bypass circuit (72) includes one or more channels (74, 76) formed in one of the flange arm (61) or the backing plate. When more than one channels are used, at least one connecting slot (80) is provided between the channels (74, 76). At least one inlet passage has an inlet port (84) which extends through the flange arm (61) in fluid communication with the forward-most channel (74), and at least one outlet slot (88) is formed between the flange arm (61) and the backing plate in fluid communication with the aft-most channel (76).

摘要： An annular air baffle (60) disposed in a cavity (50) of a rotatable gas turbine engine part includes an annular split ring (70) supporting a plurality of circumferentially spaced apart fins (72). The cavity (50) is closed at a radially outer diameter (52) and open at a radially inner diameter (56) of the part. The ring (70) and the fins (72) may be integrally formed in one piece. The fins (72) may have common surfaces (76) with the ring (70) and the common surfaces (76) may be circular cross-sectional surfaces of the ring (70) and radially outer rounded corners (82) of the fins (72). The fins (72) may have triangular cross-sectional shapes (86) with first, second, and third sides (90, 92, and 94), rounded first radially inner corners (100) between the first and second sides (90 and 92), rounded second radially inner corners (102) between the second and third sides (92 and 94), and the radially outer rounded corners (82) between the first and third sides (90 and 94). The fins (72) may extend radially inwardly from the annular split ring (70).

摘要： A gas injector system (20) includes a plenum (22) with a plenum opening (34) in the wall of the plenum (22). An injector (36) is positioned at a location overlying the plenum opening (34). The injector (36) includes an injector block (38) affixed to the exterior surface (26) of the plenum wall (24), a joint (40) between the injector block (38) and the plenum wall (24), and an angularly inclined injector passage (42) extending through the injector block (38) from an injector passage inlet (44) to an injector passage outlet (46). The injector block (38) is preferably brazed to the plenum wall (24) for high-temperature applications, or adhesively joined for low-temperature applications.

摘要： A flanged joint connection for connecting together by a bolted connection a pair of casing shells having connecting flanges (60, 74). The connection reduces bearing stress concentrations adjacent fillets (102, 106) provided at the junction of the flange (60, 74) and the casing shell surface (104, 108). A rectilinear edge portion (114, 116) is provided on a bolt head (118) or a spacer (120), or both, to avoid point contact of the bolt head (118) or spacer (120) and the flange face (90, 100) or fillet (120, 106). The rectilinear edge portion (114, 116) includes a convexly-curved surface (122, 124) that faces the fillet (102, 106). The incidence of cracks between a bolt hole (80) and the fillet (102, 106), as well as the incidence of circumferential cracks between adjacent bolt holes (80) is significantly reduced.
