초록 ▼

Described are articles, materials, and methods for protecting moving parts from degradation, such as protecting an airfoil or hydrofoil from erosion forces caused by air, sand, water, or wind. Described are foil-shaped erosion-resistant sleeves for protecting a foil. The sleeves may have a body with an outer surface, an inner surface, a thickness, a longitudinal dimension with a first end and a second end, and a dimension transverse to the longitudinal dimension, and the outer surface may include a shape-memory polymer or an elastomeric polymer with a materially continuous perimeter circumscribing the body around the transverse dimension, and an opening at the first end of the body adapted to receive the foil. Some erosion-resistant sleeves may be installed on a foil by inserting the foil into the sleeve through an opening in the sleeve, contracting the sleeve around the foil, and conforming the sleeve around the foil.

대표청구항 ▼

1. An airfoil or hydrofoil erosion-resistant sleeve for protecting a foil, the foil comprising an airfoil or hydrofoil having a first foil shape, the sleeve comprising: a body adapted to cover at least a portion of the foil, the body comprising an outer surface and an inner surface and a sleeve thickness therebetween and having a longitudinal dimension with a first end and a second end and a dimension transverse to the longitudinal dimension, the outer surface comprising a shape memory polymer or an elastomeric polymer with a materially continuous perimeter circumscribing the body around the transverse dimension and having a second foil shape, the inner surface comprising a third foil shape that has the same shape as at least a portion of the first foil shape; and an opening at the first end of the body adapted to receive the foil wherein a transverse segment of the body is adapted to undergo a contraction in the transverse dimension to conform the third foil shape to the portion of the first foil shape. 2. The sleeve of claim 1 wherein the first foil shape comprises a wing-like curvilinear foil shape or a double wedge foil shape. 3. The sleeve of claim 1 wherein the body is seamless. 4. The sleeve of claim 1 wherein the body further comprises an opening at a second end. 5. The sleeve of claim 1 wherein the body comprises a concave portion. 6. The sleeve of claim 5 wherein the concave portion comprises a non-shape memory material. 7. The sleeve of claim 1 wherein the first foil shape and the second foil shape are substantially the same. 8. The sleeve of claim 1 wherein the first foil shape and the second foil shape are different. 9. The sleeve of claim 1 wherein the first foil shape and third foil shape are substantially the same. 10. The sleeve of claim 1 wherein the third foil shape is adapted and configured to provide a lift force when the sleeve covers the foil and the foil moves relative to an air or water current. 11. The sleeve of claim 1 wherein the foil comprises a leading edge and a trailing edge and the sleeve is adapted to surround and cover the foil at a portion of the leading edge, a portion of the trailing edge, and an area between the edges. 12. The sleeve of claim 1 wherein the thickness varies from a first portion of the body to a second portion of the body. 13. The sleeve of claim 12 wherein the foil includes a rounded leading edge at the front of the foil and a trailing edge at the rear of the foil wherein the thickness is greater at the first portion corresponding to the rounded leading edge. 14. The sleeve of claim 1 wherein the foil and the inner surface of the body are substantially the same size. 15. The sleeve of claim 1 wherein the third foil shape is smaller than the first foil shape, the sleeve being further adapted to be expanded or stretched to fit over the foil. 16. The sleeve of claim 1 wherein the transverse segment of the body is adapted to undergo an expansion change from about 1% to about 75% in the transverse dimension. 17. The sleeve of claim 1 wherein the transverse segment of the body is adapted to undergo an expansion change to provide between 0.010″ and 0.25″ of clearance between the inner surface of the body and the foil. 18. The sleeve of claim 1 wherein the transverse segment of the body is adapted to undergo a contraction change from about 1% to about 75% in the transverse dimension. 19. The sleeve of claim 1 wherein the transverse segment of the sleeve is adapted to undergo a contraction change to remove between 0.010″ and 0.25″ of clearance between the inner surface of the body and the foil when the sleeve is in place over the foil. 20. The sleeve of claim 1 wherein the transverse segment of the body is adapted to undergo an expansion change in response to an expansion force to provide clearance between the inner surface of the sleeve and an outer surface of the foil, and to contract when the force is removed and thereby deliver a compressive force over the surface of the foil when the sleeve is in place over the foil. 21. The sleeve of claim 1 wherein the transverse segment of the body is adapted to contract in response to an applied stimulus.
