摘要： An apparatus and method for cooling a blade tip 90 for a turbine engine 10 can include a blade 68, such as a cooled turbine blade, having a tip rail 96, 196, 296, 396 extending beyond a tip wall 94 enclosing an interior for the blade at the tip. A plurality of film-holes can be provided in the tip rail. A flow of cooling fluid can be provided through the film-holes from the interior of the blade to cool the tip of the blade.

摘要： An apparatus and method for cooling an airfoil tip 90 for a turbine engine 10 can include a blade 68, such as a cooled turbine blade, having a tip rail 96, 196, 296, 396 extending beyond a tip wall 94 enclosing an interior for the airfoil at the tip. A plurality of film-holes 112, 212, 312, 412 can be provided in the tip rail. A flow of cooling fluid can be provided through the film-holes from the interior of the airfoil to cool the tip of the airfoil.

摘要： Methods of manufacturing or repairing a turbine blade or vane are described. The airfoil portions of these turbine components are typically manufactured by casting in a ceramic mold, and a surface made up of the cast airfoil and at the least the ceramic core serves as a build surface for a subsequent process of additively manufacturing the tip portions. The build surface is created by removing a top portion of the airfoil and the core, or by placing an ultra-thin shim on top of the airfoil and the core. The overhang projected by the shim is subsequently removed. These methods are not limited to turbine engine applications, but can be applied to any metallic object that can benefit from casting and additive manufacturing processes. The present disclosure also relates to finished and intermediate products prepared by these methods.

摘要： The present disclosure generally relates to integrated core-shell investment casting molds that provide filament structures corresponding to cooling hole patterns in the surface of the turbine blade or stator vane, which provide a leaching pathway for the core portion after metal casting. These filament structures may be linear or non-linear. 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.

摘要： A method for fabricating a ceramic mold is provided. The method includes the steps of contacting a cured portion of a workpiece with a liquid ceramic photopolymer, irradiating a portion of the liquid ceramic photopolymer adjacent to the cured portion through a window contacting the liquid ceramic photopolymer, removing the workpiece from the uncured liquid ceramic photopolymer, and repeating the steps until a ceramic mold is formed. The ceramic mold includes a first opening for creating a cast article and a second opening for receiving a support member.
