Abstract: Frame assemblies, molds, and methods for forming rotor blades are provided. A frame assembly for a rotor blade mold includes a plurality of frames, at least one of the plurality of frames movable relative to the others of the plurality of frames, and a bed supported by the plurality of frames. Movement of the at least one of the plurality of frames causes a modification of the bed along a width-wise axis. A mold for forming a rotor blade includes a frame assembly and a mold material disposed in the bed of the frame assembly.

Abstract: A casting system for forming a directionally-solidified casting component is provided. The casting system defines an axial direction, a radial direction, and a circumferential direction. The casting system includes a chamber and a baffle plate disposed within the chamber. The chamber and the baffle plate collectively define a heating zone and a cooling zone. The heating zone and the cooling zone are separated by the baffle plate. The casting system further includes a shaft and a cooling plate disposed on the shaft. The cooling plate is movable between the heating zone and the cooling zone. A mold shell is disposed on the cooling plate. The casting system further includes a cooling system for directing a coolant fluid towards the mold shell.

Abstract: A method of forming a directionally-solidified casting component using a casting system is provided. The casting system includes a chamber having a heating zone and a cooling zone separated by a baffle plate. The method includes pouring an alloy in a liquid state into a mold shell. The mold shell is positioned on a chill plate within the heating zone. The method further includes moving the mold shell from the heating zone into the cooling zone. The alloy transfers from the liquid state to a solid state within the mold shell while moving the mold shell from the heating zone to the cooling zone. The method further includes contacting the mold shell with a heat transfer member.

Abstract: A method of controlling an extent of a thermal barrier coating (TBC) sheet spall and a hot gas path (HGP) component are disclosed. The method provides an HGP component having a body with an exterior surface. Controlling the extent of the TBC sheet spall includes forming a TBC over a selected portion of the exterior surface of the body. The TBC includes a plurality of segments in a cellular pattern. Each segment is defined by one or more slots in the TBC, and each segment has a predefined area such that the extent of the TBC sheet spall is limited by the predefined area of each of the plurality of segments that constitute the TBC sheet spall.

Abstract: A method of making a preform and preform formed by the method. The method includes providing a first pre-preg ply including at least a first fiber and a first resin. The method also includes providing a second pre-preg ply including at least a second fiber and a second resin over at least a portion of the first pre-preg ply. Heat or electromagnetic radiation is used to at least partially cure the first and second resins to form a cured preform. Heat is applied to pyrolyze at least a portion of the resin of the cured preform to form a pyrolyzed preform. A mechanical stimulus including at least one of controlled drying, local explosions, or ultrasonic energy is applied to the pyrolyzed preform. The mechanically treated pyrolyzed preform is subsequently densified by melt infiltration to form a densified preform.

Abstract: The present disclosure is directed to a method for forming a passage in a composite component. The method includes forming a cavity in a fiber preform. The cavity forms a portion of the passage. The method also includes inserting a core into the cavity and placing one or more fiber plies onto the fiber preform to form a fiber preform assembly. The method further includes thermally processing the fiber preform assembly and densifying the fiber preform assembly to form the composite component. The method also includes removing the core from the composite component.
