Abstract
A system may include a structure having a leading edge and a fiber-reinforced composite cover. The fiber-reinforced composite cover may include a protective portion and a retaining portion, wherein the retaining portion extends about the structure to self-retain the protective portion along the leading edge, and the protective portion is different from the retaining portion.
Claims20
A system, comprising:
- a structure having a leading edge;
- wherein the structure comprises an airfoil, a rotary blade, a stationary vane of a rotary machine, or a combination thereof;
- and
- a fiber-reinforced composite cover comprising a protective portion and a retaining portion, wherein the retaining portion extends about the structure to self-retain the protective portion along the leading edge, the protective portion is different from the retaining portion, the protective portion comprises an outermost layer of the fiber-reinforced composite cover, and first edges of the protective portion are coupled to second edges of the retaining portion without overlap of the first and second edges.
1 more element
A system, comprising:
- a fiber-reinforced composite cover comprising a protective portion and a retaining portion, wherein the fiber-reinforced composite cover comprises at least one loop, the retaining portion is configured to self-retain the fiber-reinforced composite cover about a structure, with the protective portion comprising an outermost layer of the fiber-reinforced composite cover, the protective portion is different from the retaining portion, the protective portion comprises a first fiber-reinforced composite, and first edges of the protective portion are coupled to second edges of the retaining portion without overlap of the first and second edges.
A system, comprising:
- a turbine engine comprising a rotary blade having an edge;
- and
- a fiber-reinforced composite cover comprising a protective portion and a retaining portion defining at least one loop, wherein the at least one loop extends about the rotary blade to self-retain and self-conform the protective portion along the edge, the protective portion comprises a first fiber-reinforced composite, the protective portion and the retaining portion comprise different materials, different thickness, different hardnesses, or different densities, relative to one another, and the protective portion comprises an outermost layer of the fiber-reinforced composite cover.
