  • Positioning system and impact indicator for gas turbine engine fan blades
    Patent number: 5275536
    Abstract: A fan blade and rotor disk assembly for a gas turbine engine has a projection attached to a shank region of a fan blade. The projection makes contact with a surface region of a disk post when the fan blade is assembled to the rotor disk. In one form, a spring urges the fan blade to a position to maintain the projection in contact with the disk post surface so as to maintain the radial position of the fan blade. The projection member absorbs impact loading, shears off, allowing the blade to rotate and reduces the moment experienced by the root region of the fan blade when the fan blade is impacted by a foreign object.
