  • AIRFOIL STRUCTURES
    Publication number: 20160032939
    Abstract: An airfoil structure includes a composite core including a triaxial braid, wherein the triaxial braid includes a longitudinal axis, a first bias fiber extending in a first bias direction at a first bias angle to the longitudinal axis, a second bias fiber extending in a second bias direction at a second bias angle to the longitudinal axis, and an axial fiber extending in a direction parallel to the longitudinal axis. The airfoil structure further includes an outer layer substantially surrounding the composite core, wherein the outer layer includes a plurality of unidirectional prepreg layers.

  • Airfoils including compliant tip
    Patent number: 9085989
    Abstract: An airfoil, a fan assembly and an engine include at least one airfoil including a root portion, a body portion and a tip portion. The body portion is configured extending radially outward from the root portion and the tip portion is configured extending radially outward from the root portion and the body portion. The airfoil including a suction and a pressure side coupled together at a leading and a trailing edge and extending therebetween. The airfoil including a compliant tip at the tip portion. The compliant tip extending along at least a portion of the tip portion in a chord-wise direction and a span-wise direction. The compliant tip is configured to provide wave propagation along the tip portion such that critical strain proximate the tip portion and the trailing edge is reduced during a foreign object impact.
