Abstract
An airfoil cooling structure, an airfoil having the airfoil cooling structure, and a turbine blade/vane element including the airfoil are disclosed. The airfoil cooling structure includes a cooling path formed inside the airfoil and having a first surface and a second surface opposite to the first surface, and an additive manufactured (AM) feature disposed in the cooling path, manufactured by additive manufacturing, and including a plurality of column parts intersecting with each other so as to abut against the first surface and the second surface.
Claims20
An airfoil cooling structure comprising:
- a cooling path formed by a first surface and a second surface opposite to the first surface;
- and
- an additive manufactured (AM) feature disposed in the cooling path, manufactured by additive manufacturing, and comprising a plurality of column parts intersecting with each other and configured to contact the first surface and the second surface,
- wherein each of the plurality of column parts is formed in a cylinder shape and includes a first end face and a second end face disposed opposite to each other and a circumferential surface disposed between the first end face and the second end face, and each of the first end face and the second end face is substantially perpendicular to the circumferential surface.
An airfoil comprising:
- a suction surface, a pressure surface, a leading edge, and a trailing edge, which are externally formed on the airfoil;
- a cooling path formed inside the airfoil and having a first surface and a second surface opposite to the first surface;
- and
- an additive manufactured (AM) feature disposed in the cooling path, manufactured by additive manufacturing, and comprising a plurality of column parts intersecting with each other and configured to contact the first surface and the second surface,
- wherein each of the plurality of column parts is formed in a cylinder shape and includes a list end face and a second end face disposed opposite to each other and a circumferential surface disposed between the first end face and the second end face, and each of the first end face and the second end face is substantially perpendicular to the circumferential surface.
