Abstract
Gas turbine engines are used as powerplants for aircraft. When the aircraft are parked on the ground, the wind can blow through the engines and set fans and rotors into motion, i.e., windmill them. Given that the blades of the fans and rotors are loosely fastened to their rotors, the low speed rotation caused by windmilling causes the blades to clatter or clank, thus causing wear. The present invention provides means for clamping blades into position during this low speed rotation for reducing clanking.
