Abstract
A method and apparatus for balancing the rotor in the low pressure stage of the turbine in a jet engine comprises attaching at least one balance clip to the shroud of the rotor. The balance clip comprises a clip body formed with a forward hook portion adapted to extend over the forward rail of the shroud and an aft tab which is crimped over the aft rail of the shroud onto its outer surface so that the clip body is retained against the interior face or diameter of the shroud. The balance clip is formed of sheet material such as AMS 5596E/5597B whose weight can be varied by altering the thickness or width of the clip body, or by drilling holes in the clip body to remove material therefrom.
