Abstract
An airfoil includes an airfoil body that extends at least between leading and trailing edges, first and second sides, and radially inner and outer ends. The airfoil body includes an aluminum alloy that has a controlled crystallographic texture with respect to a predefined three-dimensional coordinate system. The airfoil can be used in the fan of a gas turbine engine.
Claims17
An airfoil comprising:
- an airfoil body extending at least between leading and trailing edges, first and second sides, and radially inner and outer ends, the airfoil body including an aluminum alloy having a controlled crystallographic texture with respect to a predefined three-dimensional coordinate system, wherein the controlled crystallographic texture defines a texture distribution with respect to volume fractions of textures.
A gas turbine engine comprising:
- a fan;
- a compressor section;
- a combustor in fluid communication with the compressor section;
- and
- a turbine section in fluid communication with the combustor,
- the fan including an airfoil having an airfoil body extending at least between a leading edge and a trailing edge, a first side and a second side, and a radially inner end and a radially outer end, the airfoil body including an aluminum-based metallic material having a controlled crystallographic texture with respect to a predefined three-dimensional coordinate system, wherein the controlled crystallographic texture includes an orientation of a high strength crystal direction within 10° of an axis of the predefined three-dimensional coordinate system and the controlled crystallographic texture defines a texture distribution with respect to volume fractions of texture components.
