Abstract
A composite airfoil assembly has a composite airfoil, a spar, and a wrap. The composite airfoil has an outer wall and a composite skin. The outer wall extends between a root and a tip. The outer wall defines an interior. The composite skin at least partially defines the outer wall. The spar having a spar centerline axis, a stem, a base, and a transition interconnecting the base and the stem.
Claims19
A composite airfoil assembly comprising:
- a composite airfoil having an outer wall extending between a root and a tip, and defining an interior, the composite airfoil having a composite skin forming at least a portion of the outer wall;
- a spar having a spar centerline axis, a stem extending into at least a portion of the interior, a base located exterior the root of the composite airfoil, and a transition interconnecting the stem and the base;
- and
- a wrap at least partially encircling the transition, the wrap contacting a respective portion of the spar and the composite airfoil.
A composite airfoil assembly comprising:
- a composite airfoil having an outer wall extending between a root and a tip, and defining an interior, the composite airfoil having a composite skin forming at least a portion of the outer wall;
- a spar having a spar centerline axis, a stem extending into at least a portion of the interior, a base located exterior the root of the composite airfoil, and a transition interconnecting the stem and the base;
- and
- a wrap at least partially encircling the transition;
- wherein the composite skin extends axially over the transition with respect to the spar centerline axis, and the composite skin is located radially between the wrap and the transition with respect to the spar centerline axis.
A composite airfoil assembly comprising:
- a composite airfoil having an outer wall extending between a root and a tip, and defining an interior, the composite airfoil having a composite skin forming at least a portion of the outer wall;
- a spar having a spar centerline axis, a stem extending into at least a portion of the interior, a base located exterior the root of the composite airfoil, and a transition interconnecting the stem and the base;
- and
- a wrap at least partially encircling the transition;
- wherein the wrap extends axially beyond the transition and over at least a portion of the composite skin.
A composite airfoil assembly comprising:
- a composite airfoil having an outer wall extending between a root and a tip, and defining an interior, the composite airfoil having a composite skin forming at least a portion of the outer wall;
- a spar having a spar centerline axis, a stem extending into at least a portion of the interior, a base located exterior the root of the composite airfoil, and a transition interconnecting the stem and the base;
- a first wrap at least partially encircling the transition including a metallic material;
- and
- a second wrap at least partially encircling the first wrap, the second wrap including a composite material.
A composite airfoil assembly comprising:
- a composite airfoil having an outer wall extending between a root and a tip, and defining an interior, the composite airfoil having a composite skin forming at least a portion of the outer wall;
- a spar having a spar centerline axis, a stem extending into at least a portion of the interior, a base located exterior the root of the composite airfoil, and a transition interconnecting the stem and the base;
- and
- a wrap at least partially encircling the transition;
- wherein the wrap includes circumferentially distal ends with a gap formed therebetween.
