Abstract
An airfoil assembly may include a shroud and an airfoil. The shroud may include a first attachment arm, a second attachment arm, and a shroud rail extending from a first surface of the shroud. A first channel may be defined between the first attachment arm, the first surface, and the shroud rail and a second channel may be defined between the second attachment arm, the first surface, and the shroud rail. The airfoil may extend from a second surface of the shroud opposite the first surface. In various embodiments, a height of the shroud rail, as measured from the first surface of the shroud, is non-uniform.
Claims20
An airfoil assembly comprising:
- a shroud comprising a first attachment arm, a second attachment arm, and a shroud rail extending from a first surface of the shroud, wherein:
- a first channel is defined between the first attachment arm, the first surface, and the shroud rail;
- and
- a second channel is defined between the second attachment arm, the first surface, and the shroud rail;
- and
- an airfoil extending from a second surface of the shroud opposite the first surface.
A gas turbine engine comprising:
- a case structure;
- and
- an airfoil assembly comprising a shroud and an airfoil, wherein the airfoil assembly is mounted to the case structure via a first attachment arm and a second attachment arm of the shroud of the airfoil assembly, wherein a shroud rail of the shroud partially extends between the first attachment arm and the second attachment arm.
A manufacturing method comprising:
- forming a shroud rail extending from a first surface of a shroud of an airfoil assembly;
- forming an airfoil extending from a second surface of the shroud opposite the first surface;
- and
- shaping the shroud rail to tune an aeromechanical response of the airfoil assembly.
