A method and device for thermal creep-sizing an annular-shaped structure. The creep-sizing device includes a ring member with through-holes present between the inner and outer diametrical boundaries of the ring member, and with through-slots alternatingly extending from each through-hole to either the inner or outer diametrical boundary. In use, the ring member is placed within the annular-shaped structure, and pins are installed in the through-holes in the ring member to cause the outer diametrical boundary of the ring member to diametrically expand. The structure and creep-sizing device are then heated so that the mechanically expanded ring member causes the structure to undergo thermal creep-sizing.

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.
