Fan blade dovetail with compliant layer
A fan blade includes an airfoil and a dovetail at a radially inner end of the airfoil. The dovetail extends between first and second axial ends, and has outer circumferential faces. The dovetail is formed of relatively rigid composite material. Compliant material is placed on each outer circumferent...

| description | A fan blade includes an airfoil and a dovetail at a radially inner end of the airfoil. The dovetail extends between first and second axial ends, and has outer circumferential faces. The dovetail is formed of relatively rigid composite material. Compliant material is placed on each outer circumferential face of the dovetail. The compliant material is less rigid than the composite material for forming the dovetail. In a second embodiment, the compliant layer may be positioned within the disk slots in a disk, such that the compliant layer will come in contact with circumferentially outer faces of the dovetail. |
