ABSTRACT:
The span of the overhung flanges at the rim of the disks of gas turbine engine's compressors are minimized by slotting the one of the adjacent flanges at the distal end to receive the bolt head of the attaching bolt and including an anti-rotational clip allowing the nut to be fastened without the necessity of holding the bolt head. The complementing flange of the adjacent rotor includes mating holes. The anti-rotational clip includes bendable tangs bent in situ to engage the flats of the bolt head and a bent tang to fit snugly into the when radially inserted therein slot.
