Abstract
An airfoil includes an airfoil section that defines an airfoil profile. The airfoil section includes a panel that forms a portion of the airfoil profile and a core structure to which the panel is secured.
Claims22
An airfoil comprising:
- an airfoil section defining an airfoil profile, the airfoil section including
- a panel that forms a portion of the airfoil profile, the panel including a geometrically segmented coating section, the geometrically segmented coating section including a wall that has an outer side, the outer side including an array of closed-sided cells defined by cell sidewalls, and a coating disposed in the array of closed-sided cells, and
- a core structure to which the panel is secured.
A gas turbine engine comprising:
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor,
- at least one of the turbine section or the compressor section including an airfoil having an airfoil section defining an airfoil profile, the airfoil section including
- a panel that forms a portion of the airfoil profile, the panel including a geometrically segmented coating section, the geometrically segmented coating section including a wall that has an outer side, the outer side including an array of polygonal cells defined by cell sidewalls, and a coating disposed in the array of polygonal cells, and
- a core structure to which the panel is secured.
4 more elements
A method of assembling an airfoil, the method comprising:
- securing a panel to a core structure to form an airfoil section, wherein the airfoil section has an airfoil profile and the panel defines a portion of the airfoil profile, the panel including a geometrically segmented coating section, the geometrically segmented coating section including a wall that has an outer side, the outer side including an array of closed-sided cells defined by cell sidewalls, and a coating disposed in the array of closed-sided cells.
