Abstract
A special tool in intermediate form, comprising: at least one aft core module having at least one aft alignment aperture and at least one baffle; a forward core having at least one forward alignment aperture, the at least one aft core module and the forward core disposed adjacent to and aligned with one another; at least one alignment tool disposed within each at least one aft alignment aperture, and aligned with and also disposed within each at least one forward alignment aperture; and a preform material disposed about the adjacent, aligned aft core and forward core.
Claims20
A special tool in intermediate form, comprising:
- at least one aft core assembly having at least one aft alignment aperture and at least one baffle;
- a forward core assembly having at least one forward alignment aperture, the at least one aft core module and the forward core disposed adjacent to and aligned with one another;
- at least one alignment tool disposed within each at least one aft alignment aperture, and aligned with and also disposed within each at least one forward alignment aperture;
- and
- a preform material disposed about the adjacent, aligned aft core and forward core.
A process for fabricating a special tool, comprising:
- fabricating an aft core assembly;
- fabricating a forward core assembly;
- assembling together the aft core assembly and the forward core assembly using at least one alignment tool to form an assembled core;
- disposing at least one preform material about at least a portion of an exterior surface of the assembled core;
- disposing the assembled core within a cavity of a gas turbine engine component having an airfoil;
- and
- densifying gas turbine engine component to form at least one cooling circuit and at least one porous network within the assembled core.
A process for fabricating at least one cooling circuit and at least one porous network within a gas turbine engine component, comprising the steps of:
- fabricating an aft core assembly;
- fabricating a forward core assembly;
- assembling together the aft core assembly and the forward core assembly using at least one alignment tool to form an assembled core;
- disposing at least one preform material about at least a portion of an exterior surface of the assembled core;
- disposing the assembled core within a cavity of a gas turbine engine component having an airfoil;
- and
- densifying gas turbine engine component to form the at least one cooling circuit and the at least one porous network within the assembled core of the gas turbine engine component.
