Abstract
A split case is provided. The split case includes a first section including an interior surface with a first linear portion, a second section including a hook, a third section interposed between the first and second sections and including an interior surface with a second linear portion intersecting and forming a first angle with the first linear portion and first and second thermal barrier coating (TBC) portions applied to at least the first and second linear portions, respectively. A magnitude of the first angle is established such that the first and second TBC portions form a second angle substantially equal to the first angle.
Claims9
A split case formation method, comprising:
- casting a split case comprising first, second and third sections, the first section comprising an interior surface with a first linear portion, the second section comprising a hook and the third section being interposed between the first and second sections;
- and
- machining the third section to form an interior surface, the interior surface comprising:
- a second linear portion such that the second linear portion intersects and forms an angle with the first linear portion at an intersection point of the first and second linear portions;
- and
- a curved portion leading from an end of the second linear portion, which is opposite from the angle, to a linear interior surface of the hook,
- wherein the machining comprises:
- positioning a machining tool in position to machine the third section;
- moving the machining tool in a linear pathway along the third section to form the second linear portion and the curved portion;
- and
- maintaining an orientation of the machining tool during an entirety of the machining.

- casting a split case comprising first, second and third sections, the first section comprising an interior surface with a first linear portion, the second section comprising a hook and the third section being interposed between the first and second sections;
- and
- machining the third section to form an interior surface, the interior surface comprising:
- a second linear portion such that the second linear portion intersects and forms an angle with the first linear portion at an intersection point of the first and second linear portions;
- and
- a curved portion leading from an end of the second linear portion, which is opposite from the angle, to a linear interior surface of the hook,
- wherein the machining comprises:
- positioning a machining tool in position to machine the third section;
- moving the machining tool in a linear pathway along the third section to form the second linear portion and the curved portion;
- and
- non-rotatably maintaining an orientation of the machining tool during an entirety of the machining.
A split case formation method, comprising:
- casting a split case comprising first, second and third sections, the first section comprising an interior surface with a first linear portion, the second section comprising a hook and the third section being interposed between the first and second sections;
- and
- machining the third section to form an interior surface, the interior surface comprising:
- a second linear portion such that a proximal straight end of the second linear portion intersects and forms a first angle with a proximal straight end of the first linear portion at an intersection point of the respective proximal straight ends of the first and second linear portions;
- and
- a curved portion leading from an end of the second linear portion, which is opposite from the angle, to a linear interior surface of the hook,
- wherein the machining comprises:
- positioning a machining tool in position to machine the third section;
- moving the machining tool in a linear pathway along the third section to form the second linear portion and the curved portion;
- and
- non-rotatably maintaining an orientation of the machining tool during an entirety of the machining.
