Abstract
An airfoil includes an airfoil section that defines an airfoil profile. The airfoil section includes a distinct panel that forms a portion of the airfoil profile. The panel has a geometrically segmented coating section. The geometrically segmented coating section includes a wall that has an outer side. The outer side includes an array of cells, and there is a coating disposed in the array of cells.
Claims21
An airfoil comprising:
- an airfoil section defining an airfoil profile, the airfoil section including a core skeleton, a distinct panel attached with the core skeleton and forming a portion of the airfoil profile, the distinct panel having a geometrically segmented coating section, the geometrically segmented coating section including
