  • Gas turbine engine fan blade assembly
    Patent number: 5443366
    Abstract: A fan blade assembly for a ducted fan gas turbine engine comprises a hub which carries an annular array of radially extending fan blades. Each fan blade has a root portion which locates in a corresponding groove in the hub. Aligned radial slots in the root portion and groove accommodate a U-shaped key which provides axial retention of the root portion in its groove. A flat spring attached to the underside of the root portion maintains the key in position and permits manual deflection of the key to assist blade assembly and disassembly.
