    Abstract: A fan blade capable of dissipating a buildup of electrostatic charge configured for operation within the fan assembly of a gas turbine engine. The fan blade has a fan blade body covered in a static dissipative coating. A conductive ground tab is attached to the front face of an airfoil root of the fan blade. Connected to the ground tab, a conductive flow path travels up the neck portion of the airfoil and along a lower portion of the fan blade. As static charge builds up on the fan blade, the electrostatic charge migrates down the fan blade and into the conductive flow path. Traveling along the conductive flow path the buildup of electrostatic charge accumulates on the conductive ground tab and exits the fan blade through contact with a disc rotor covering touching the conductive ground tab.

    Abstract: A fan assembly is disclosed which includes a rotor having an outer periphery and at least one slot extending radially inwardly through the outer periphery. The slot terminates at a base surface disposed at a radial depth from the outer periphery of the rotor. The fan assembly also includes at least one fan blade that includes an airfoil connected to a root. The root is received in the slot. The root terminates in an inner face having a radial length that is less than the radial depth of the Slot to define a gap between the inner face of the root and the base surface of the slot when the root is bias away to the base surface of the slot. A spacer is disposed within a gap, wherein a spacer is fabricated from a polymer, which may be a composite material such as a polymer embedded with reinforcing materials such as carbon fibers and glass fibers.
