Abstract

See full text

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.
