Abstract: An apparatus and method for an airfoil for a gas turbine engine includes a trailing edge cooling circuit utilizing a plurality of trailing edge ejection holes. The ejection holes can include a circumferentially radiused inlet, a converging section, a metering section, and a diverging section to improve airfoil cooling as well as castability.

Abstract: The present disclosure generally relates to partial integrated core-shell investment casting molds that can be assembled into complete molds. Each section of the partial mold may contain both a portion of a core and portion of a shell. Each section can then be assembled into a mold for casting of a metal part. The partial integrated core-shell investment casting molds and the complete molds may be provided with filament structures corresponding to cooling hole patterns on the surface of the turbine blade or the stator vane, which provides a leaching pathway for the core portion after metal casting. The invention also relates to core filaments that can be used to supplement the leaching pathway, for example in a core tip portion of the mold.

Abstract: A method of casting a truss structure having spaced face sheets connected by columnar structures, including forming a three-dimensional pattern (3D pattern) in the shape of the truss structure with the spaced face sheets and columnar structures, forming a mold core of the 3D pattern by surrounding the pattern with a liquid and letting the liquid harden about the 3D pattern, removing the 3D pattern from the mold core, filling the mold core with a liquid alloy to cast and directionally solidify the truss structure.
