    摘要： A method of manufacturing a core for casting a component (20) can include manufacturing a core for at least partially forming an internal passage architecture of a component with a material including radiopaque particles. A method can include removing a material including radio opaque particles from an internal passage architecture of a component; and inspecting the component via radiographic imaging at gamma/X-ray wavelengths to detect residual material. A core for use in casting an internal passage architecture of a component can include a material with radiopaque particles dispersed therein.

    摘要： A method of forming a component (100) includes the steps of placing a core (110) into a mold (118,120) and pouring a component material (122) around the core (110). The component material (122) is allowed to solidify. The core (110) is then removed from within the material (122), leaving a component (100) having at least a first (102) and a second (104) cavity formed by the core (110). A first filler material (128) is moved into the first cavity (102), and a second filler material (126) is moved into the second cavity (104). The component (100) is inspected for the presence of an apparent residual core (132,138) within the first cavity (102) and the second cavity (104). The location is identified of the apparent residual core (132,138) from the core (110) based upon an identification of whether the location of the apparent residual core (132,138) is in the first (128) or second (126) filler materials.

    摘要： A gas turbine engine component (60) has a component body (66) configured to be positioned within a flow path (80) of a gas turbine engine, wherein the component body (66) includes at least one internal cavity (78). At least one inlet opening (82) is formed in an outer surface (84) of the component body (66) to direct flow into the at least one internal cavity (78). At least one outlet (86) from the internal cavity (78), wherein the at least one outlet (86) is located at a lower pressure area in the internal cavity (78) than the at least one inlet opening (82) such that flow is drawn into the internal cavity (78) from the at least one inlet opening (82) and expelled out the at least one outlet (86).

    摘要： A blade outer air seal (106) includes a seal body that has a channel (122, 222) on a radially inner side (R1) that defines a first height portion within the channel (122, 222) and a second height portion outside of the channel (122, 222). A first cavity (124, 224) is in the first height portion and a second cavity (124, 224) is in the second height portion. An abradable coating (116) is over the radially inner side (R1) and fills the first and second cavities (124, 224).

    摘要： A turbine airfoil (60) includes an airfoil outer wall (66) that defines leading and trailing ends (LE,TE) and first and second sides (68a,68b) that join the leading and trailing ends (LE,TE). At least one cooling passage (74) is embedded in the airfoil outer wall (66) and has a radially-elongated entrance manifold (76), a radially-elongated diffuser orifice (78) that opens to an exterior surface of the airfoil outer wall (66), and a bank of sub-passages (80) fluidly connecting the radially-elongated entrance manifold (76) with the radially-elongated diffuser orifice (78). The radially-elongated diffuser orifice (78) is sloped relative to the radially-elongated entrance manifold (76).
