ABSTRACT:
Apparatus for increasing the twist of blades of an integrally bladed rotor comprise a plurality of pairs of opposed, aligned blade formers, slideably disposed in guide channels on opposite sides of the blades to be twisted. The rotor and twisting apparatus is heated and the opposed formers are forced toward each other. The blade disposed between each pair of formers is sandwiched between the ends of the formers. The ends of the formers are specially shaped such that the blades are reshaped or twisted to the desired final contour.
