    摘要： A method of manufacturing a cooled gas turbine component includes forming a core with an outer surface. The outer surface includes a core feature. The method also includes casting an outer wall of an airfoil about the core. The outer wall has an exterior surface and an interior surface. The interior surface includes a shaped inlet portion that corresponds to the core feature. Moreover, the method includes forming an outlet portion through the outer wall to fluidly connect the outlet portion to the shaped inlet portion. The shaped inlet portion and the outlet portion cooperatively define a cooling aperture through the outer wall.

    摘要： A process for creating a lost wax tree, including the steps of assembling a wax tree having a wax pattern and a wax runner, using automated equipment to flex either the wax tree or the wax pattern to bring disconnected sections into proximity, heating at least one of the disconnected sections, contacting the disconnected sections and then moving the sections slightly away from one another. A process for casting a part including the steps of creating a lost wax tree and where the wax tree is later covered with a mold material and the wax tree is removed to create a mold, the mold is then used to cast a part similar to the wax pattern. A lost wax tree having a wax tree with a wax pattern and a wax runner, automated equipment for flexing, a heating element, and automated equipment for manipulating disconnected sections.

    摘要： The invention relates to the field of lost-pattern casting and more specifically to a casting tree (1) for lost-pattern casting, and the method of assembly thereof. This casting tree (1) comprises at least one component support (8), at least one pattern (2), and at least a first male - female connection (9) connecting said pattern (2) to the component support (8). Said first male - female connection (9) comprises an orifice (13), a pin (11) at least partially inserted into the orifice (13), and a thin film (15) of a material that can be melted interposed at least between an external surface (11a) of the pin (11) and an internal surface (13a) of the orifice (13).
