Abstract
A vane includes an airfoil that defines a leading edge, a trailing edge, a pressure side, and a suction side. The airfoil includes a truss structure that has ribs that define there between a plurality of through-cavities from the pressure side to the suction side. Honeycomb cells are disposed in the cavities. A face sheet defines at least one of the pressure side or the suction side. The face sheet has perforations that correspond in location to the honeycomb cells.
Claims20
A vane comprising:
- an airfoil defining a leading edge, a trailing edge, a pressure side, and a suction side, the airfoil including a truss structure having ribs that interconnect with each other and that define there between a plurality of through-cavities from the pressure side to the suction side;
- honeycomb cells disposed in the plurality of through-cavities;
- wherein each honeycomb cell is defined by a closed-perimeter side wall;
- and
- a face sheet defining at least one of the pressure side or the suction side, the face sheet having perforations corresponding in location to the honeycomb cells.
