Impact tolerant composite airfoil for a turbine engine

摘要

A composite airfoil (14a) includes a core (36) that has a three-dimensional network of fibers. The core (36) defines an airfoil section (30) and a root section (32). A composite skin (38) covers a portion of the core (36) excluding the root section (32). A method for use with a composite airfoil (14a) uses that composite skin (38) for managing foreign object impact tolerance of the composite airfoil thereby establishing a different impact tolerance on the root section (32) than on the portion of the cove (36) that is covered with the composite skin (38).
